Opis:: Present study describes about the effect of coolant water flow rate and coolant water temperature underside cooling slope on structural characteristics of casted AZ91 Mg alloy. Here, over the cooling slope, hot melt flows from top to bottom. Additionally, under the cooling slope, coolant water flows from bottom to top. Slurry gets obtained at bottom of cooling slope by pouring AZ91 Mg melt from top of the slope. Coolant water flow rate with coolant water temperature underside cooling slope warrant necessary solidification and shear to obtain AZ91 Mg slurry. Specifically, slurry at 5 different coolant water flow rates (4, 6, 8, 10, 12 lpm) and at 5 different coolant water temperatures (15, 20, 25, 30, 35°C) underside cooling slope are delivered inside metal mould. Modest coolant water flow rate of 8 lpm with coolant water temperature of 25°C (underside cooling slope) results fairly modest solidification that would enormously contribute towards enhanced structural characteristics. As, quite smaller/bigger coolant water flow rate/temperature underside cooling slope would reason shearing that causes inferior structural characteristics. Ultimately, favoured microstructure was realized at 8 lpm coolant water flow rate and 25°C coolant water temperature underside cooling slope with grain size, shape factor, primary α-phase fraction and grain density of 63 µm, 0.71, 0.68 and 198, respectively. Correspondingly, superior mechanical properties was realized at 8 lpm coolant water flow rate and 25°C coolant water temperature underside cooling slope with tensile strength, elongation, yield strength and hardness of 250 MPa, 8%, 192 MPa and 80 HV, respectively.

Opis:: In this article has been found that the most popular and widely used method of cooling is liquid cooling, which ensures uniformity of temperature around the combustion chamber and easy acquisition and transfer of heat, although the properties of water are limited by maximum temperature of the coolant. Preliminary scientific research of such a system indicates the possibility of increasing overall efficiency and reducing toxic components in exhaust gases at low engine loads when the engine exhaust temperature of the classic system is too low for efficient catalytic action. This paper presents the dynamometer test stand designed and built using original components of diesel engine 4CT90 production of WSW "ANDORIA" SA. Presented system was designed for the four cylinder with indirect fuel injection system. Research was made on the engine dynamometer stand, which was equipped with standard measure devices (measures: speed, torque, temperatures, flows) and exhaust gas analysers. The temperature of this liquid was increased to the higher level than temperature of boiling water in normal conditions. Overpressure inside the cooling system was limited to 0.3 MPa, the temperature inside the cooling system was increased to 115–120°C. During the test, the cooling system was filled with coolant at 90%. The selected results of investigations of the cooling system for the combustion engine working with higher temperature of the cooling liquid, where the influence of speed and load on the engine temperature were presented.

Opis:: The selected results of investigations of the cooling system for the combustion engine working with higher temperature of the cooling liquid were presented. The temperature of this liquid were increased to the temperature of boiling water, as a basic compound of the cooling liquid. This system was designed for the four cylinder diesel engine 4CT90 with indirect fuel injection system. Investigation was realized on the dynamometer stand equipped with standard measure devices (measures: speed, torque, temperatures, flows) and exhaust gas analyzers. The speed and torque engine characteristics were determined. The over pressure inside cooling system was limited up to 0.07 MPa regarding lower pressure structural integrity of the standard units of this system. Intensity of the cooling, protective against too higher pressure, were changed by switching small and full liquid circulation, and one or two fans of the cooler. temperature inside cooling system was increased up to 110 centigrade. Results ofincreasing of the cooler temperature were lower frictions of unburned products of combustion process (CO and HC) in the exhaust gas (up to 50%) in low torque and low engine speed. This is area when catalytic reactor does not work because too low is exhaust gas temperature. It wasfound that engine economy was increased to 7% in maocimum load and high engine speed.

Opis:: In recent years, titanium alloys and nickel alloys have become eminent for making aeronautic and astronautic parts. Since both nickel and titanium alloys have a very small thermal conductivity, the being used tool will suffer from huge damage by heat generated during the grinding process. Therefore, there is a requirement for a durable tool with excellent cooling capacity. In this research, the technology regarding the new forced cooling using with high-pressure coolant for machining difficult-to-machine material was developed and evaluated. A through-hole in the near the tip on the rake face of the turning tool is firstly machined by electrical discharge machining. High-pressure coolant was then supplied to the turning tool from the hole on the bottom of the tool. Several values of pressure were tried in many experiments. It is concluded from the results that; (1) a new forced cooling method in the form of drilling a hole at the tip of the tool from which supply high-pressure coolant, a tool temperature decrease and a tool-life prolongation could be achieved, (2) the technology could effectively cool near the tip of turning tool, (3) the chip was effectively broken by the high pressure, (4) It was confirmed that the tool cutting edge condition was stabilized, the surface roughness of the machined workpieces was improved, the tool hardness was maintained and the tool-life was prolonged due to the cooling effect of the devised tool.

Opis:: In the paper a model test stand designed and built using original components of diesel engine 4CT90 is presented. The stand provides working conditions as close as possible to the exploitation conditions of the engine cooling system. This applies both to the intensity of heat inside the cylinders of the engine, the temperature uniformity along the cylinder axis, as well as variable-speed water pump. Research carried out on the model stand were aimed at checking the operation of the cooling intensity control with varying levels of filling of the cooling system and develop a control method of the cooling system before testing on the dynamometer stand. In addition, system operation at elevated cooling liquid pressure for the possibility of obtaining the elevated coolant temperature were checked. The influence of working conditions on the level of the temperature was also analysed. In this paper, the characteristics selected for two values of pressure, for 0.15 MPa and 0.2 MPa, and for two different values of the degree of filling of the cooling liquid were presented. During the warming-up and continuous heating of the cylinder and the cylinder head by electrical heaters, temperature and overpressure courses before and after the liquid radiator, temperature before the inlet and outlet of the liquid from the engine and the temperature at selected points inside the engine water jacket are designated. The results of measurements of the coolant pump flow at different speed water pump were also presented in this paper.

Opis:: The paper deals with the optimization of the charge air intercooler of the turbocharged internal combustion engine with the focus on the extremely low temperatures of charge air. The software Fluent is used for the numerical simulation (CFD - Computational Fluid Dynamics) of the charge air flow. The 3 D space geometrical model of the charge air intercooler is created in the CAD (Computer Aided Design) software CATIA. The model is simplifled according to the requirements of the computational mesh creation and numerical simulation. The model is then exported as the iges file and this file is subsequently imported into the preprocessor Gambit. The imported model is repaired and a suitable mesh is then created according to the computational means properties. The last step is the definition of the types of boundary conditions. The needed types of boundary conditions are applied to the single surfaces and volumes. The completed computational mesh is then exported from Gambit and imported into the CFD software Fluent for numerical simulation. The needed values of parameters are used for the calculation definition and the simulation is started. The simulation results show the charge air flow in the charge air cooler and the places with the maximum values of turbulences can be found and this information can be the input for the optimization design of the mentioned cooler.

Opis:: Cavitation erosion of cylinder liner seriously affects the operational reliability and service life of heavy-duty diesel engines. The accuracy of the modeling-based cavitation risk evaluation is limited by the unclear correspondence between cylinder liner vibration and coolant cavitation. This report is intended to investigate the correspondence between cylinder liner vibration and coolant pressure by combining vibration cavitation test, pressure gradient calculation, and visualization observation. The cavitation risk of the cylinder liner under the piston slap is quantitatively analyzed based on a nonlinear structural dynamics model that incorporates the piston-cylinder liner nonlinear collision, piston thermal deformation, and preload of cylinder head. The results show that the occurrence of cavitation will cause a nonlinear relationship between the cylinder liner acceleration and the coolant pressure. The engine under study has a high risk of cavitation when the cylinder liner acceleration exceeds 1189 m/s2. The difference in cavitation risk for each cylinder is related to the structural modal characteristics of the crankcase. In addition, the effect of piston-liner clearance and piston pin offset on the cavitation risk is investigated based on the dynamics model.

Opis:: The paper presents the problem of the regeneration of coolants used in industrial cooling systems by investigating physic-chemical properties of used coolants and solid particle content. It was found that the used coolant is contaminated with solid particles, products of condensation, chemical products of the fluid’s aging process, products of corrosion, and elements of the cooling system. This contamination of fluids prevents its regeneration by relatively simple methods that can be implemented by a user. It is possible to recover glycol and optionally water from the used coolants. Currently, the most suitable methods for regeneration are hybrid membrane techniques.
W artykule przedstawiono problematykę regeneracji przepracowanych cieczy niskokrzepnących z układów chłodniczych instalacji przemysłowych. Dokonano oceny właściwości fizykochemicznych eksploatowanej cieczy niskokrzepnących oraz zbadano zawartość w niej zanieczyszczeń stałych. Stwierdzono, że eksploatowana ciecz jest zanieczyszczona cząstkami ciał stałych, produktami kondensacji, chemicznymi produktami starzenia jej składników oraz produktami korozji elementów instalacji chłodniczej. Tak różnorodne zanieczyszczenie cieczy uniemożliwia jej pielęgnację względnie prostymi metodami, możliwymi do realizacji u użytkownika. Ze zużytej cieczy niskokrzepnącej możliwy jest jedynie odzysk glikolu i, ewentualnie, wody. Obecnie najbardziej odpowiednie do tego celu są hybrydowe techniki membranowe.

Opis:: A mathematical and numerical model of hardening process using the generalized finite difference method for the movement of fluid and heat transport have been proposed in this paper. To solve the Navier-Stokes equation the characteristic based split scheme (CBS) has been used. The solution of the heat transport equation with the convective term has been obtained by a stabilized meshless method. To determine of the phase transformation the macroscopic model built on the basis of CCT diagrams for continuous cooling of medium-carbon steel has been used. The temporary temperature fields, the phase transformation, thermal and structural strains for the heat treated element and the fields of temperature and velocity for the coolant have been determined. The comparative analysis of the results of calculations for the model without taking into account movement of coolant has been carried out. The effect of the notch in the shaft on the cooling rates and fields of the kinetics of the phase transformations has been presented.

Opis:: The thermostat is a crucial component of a car's internal combustion engine's cooling system. Failure of the thermostat can result in undercooling or overheating of the engine. Undercooling may increase wear of engine components due to poor lubrication and lead to higher fuel consumption. Conversely, overheating can damage the engine. The engine coolant temperature is one of the fundamental parameters for the proper functioning of the engine. The vehicle's onboard diagnostics system was unable to detect the malfunction of the thermostat. As a consequence, fuel consumption increased, which was especially noticeable in winter. This paper evaluates the possibility of carrying out thermostat diagnostics using data obtained from the OBD system through a diagnostic interface ELM327, which is connected to the OBD-II connector and interfaced with Torque Pro software on a smartphone. Analysis of the data confirmed that the proposed diagnostic method was appropriate. Furthermore, the impact of the thermostat malfunction on different factors such as coolant temperature, cold engine warm-up time, parameters characterising thermostat cycling, and fuel consumption of the car were studied. It was found that, apart from the already mentioned decrease in coolant temperature, the thermostat hysteresis also decreased and the thermostat cycle time increased.

Opis:: Chemistry - radiochemistry, radiation chemistry and nuclear chemical engineering play a very important role in the nuclear power development. Even at present, the offered technology is well developed, but still several improvements are needed and proposed. These developments concern all stages of the technology; front end, reactor operation (coolant chemistry and installation components decontamination, noble gas release control), back end of fuel cycle, etc. Chemistry for a partitioning and a transmutation is a new challenge for the chemists and chemical engineers. The IVth generation of nuclear reactors cannot be developed without chemical solutions for fuel fabrication, radiation-coolants interaction phenomena understanding and spent fuel/waste treatment technologies elaboration. Radiochemical analytical methods are fundamental for radioecological monitoring of radioisotopes of natural and anthropological origin. This paper addresses just a few subjects and is not a detailed overview of the field, however it illustrates a role of chemistry for a safe and economical nuclear power development.

Opis:: A thermal neutron absorption technique has been improved with the aid of Monte Carlo N-particle (MCNP) modelling and used for the determination of the mass fraction of 10B in boric acid. A relative standard deviation of that determination has been estimated to be below 0.12%. Owing to the good precision and simplicity, the presented technique could be helpful in nuclear plants with pressurized water reactors, where boric acid is added to the primary circuit coolant to control the chain reaction. Possible applications include the checking of the actual mass fraction of 10B in lots of boric acid delivered to nuclear power plants as well as calibration of instruments used for on-line monitoring the content of 10B in reactor coolants.

Opis:: The article discusses the problem how forced air flow is implemented through the cooling module of heavy-duty engines. The kinematic connection between the coolant pump and the crankshaft of the engine, results in the fact that the pump performance often does not correspond to the engine demand at its part load. In conjunction with the fan drive method, the temperature of the coolant may be too low or too high for part load. The study was carried out in order to calculate the parameters of the cooling system in heavy-duty engines for maximum power and maximum torque, taking into account a mechanical fan drive, a hydraulic fan drive and an electric fan drive.
