Opis:
The article is devoted to temperature changes in the ground massif with the horizontal heat exchanger as an energy source for a heat pump. The article was aimed at analyzing temperature changes in the ground massif with the horizontal heat exchanger at the beginning, in the course of and at the end of the heating season. Another aim was to analyze temperature differences in the area of the horizontal exchanger and the reference lot. The heat flow utilized in the evaporator of heat pump was extracted from the ground exchanger (nominal output at the condenser was 10.5 kW). Temperatures of the ground massif with the horizontal heat exchanger were measured in its plane in depths of 0.75 m, 0.5 m and 0.25 m. The temperature inside the ground massif on the reference lot and ambient parameters were measured as well. It is obvious that the difference of energetic potentials inside the ground massif with the heat exchanger and on the reference lot is insignificant at the beginning of the heating season. During the heating season, the difference of ground massif energetic potentials increases; at the end it is constant. The difference of temperatures in horizontal planes was not significant at the beginning of the heating season; however, it gradually increased. Maximum differences were detected in the area of the heat exchanger. In higher strata, the difference between temperatures decreases. During a major part of the heating season, temperatures at pipes of the ground exchanger were negative. This fact affected amounts of heat extracted from the ground massif.

Opis:
The paper deals with assessment of thermal fields and temperature changes in ground massif with horizontal heat exchanger used as a heat source for a heat pump. Temperatures in the zone of the horizontal ground exchanger are compared with temperatures in a reference land. Changes of heat potential of the soil during the heating period are also assessed. Possibilities of recovery of thermal potential of the ground massif when utilizing vertical and horizontal exchangers are analyzed in the opening part of the paper. The results of the first verification indicated that average temperatures in the horizontal planes of the ground massif did not differ considerably with distance from the exchanger tube. Differences in average temperatures in reference and experimental lands confirmed sufficient heat potential of the ground massif even at the peak of the heating period. The differences in average temperatures reached up to 6.51 K in the end of the heating period while at the beginning of the heating period, the differences in average temperatures dropped to 1.35 K. The differences between maximum and minimum temperatures in the zone of the ground exchanger reached up to 1.9 K at the peak of the heating period and rose to 3.9 K at the beginning and end of the heating period. The first results of our measurements indicate the necessity of accumulation of thermal energy in the soil massif in the summer period like in case of the vertical exchangers.

Opis:
Most of the formulations regarding the characteristics of a shell and tube heat exchanger have a common assumption; namely that the baffle plates are equidistant. This assumption fails to cater the real world scenario for defective baffles as the alteration in a shell and tube heat exchanger invalidates the equidistant baffle spacing of the plates. In this regard, a small six baffles heat exchanger was modeled in the computational fluid dynamics software package and studied by removing each baffle plate one at a time. Effect of removing each baffle plate on the temperature, pressure, heat transfer coefficient, and total heat transfer rate was recorded. It was observed that variation in the pressure drop for the same number of baffle plates varies along the axial order of the plates. The change in pressure drop due to the removal of the baffle plate near the inlet and the outlet was lowest and reaches a maximum in the axial center. It was also found that the plates below the radial center contribute higher towards the overall heat transfer as compared to those above.

Opis:
Artykuł poświęcony jest zagadnieniu przepływu ciepła w czasie skrawania ortogonalnego stali C45 ostrzem węglikowym bez powłok ochronnych. W badaniach modelowych, do wyznaczenia zmian rozkładu temperatury oraz wartości średniej i maksymalnej temperatury kontaktu, zastosowano zmodyfikowaną metodę różnic skończonych. Badano zmiany dystrybucji temperatury w strefie skrawania wynikające z różnej konfiguracji kształtu strumienia ciepła generowanego na płaszczyźnie poślizgu oraz na długości kontaktu wiór-powierzchnia natarcia. Symulacje rozpływu ciepła prowadzono w oparciu o uproszczony model przepływu ciepła zakładający liniowe źródła ciepła o zmiennej intensywności wzdłuż całej swojej długości. Wyniki symulacji porównywano z danymi literaturowymi oraz wynikami eksperymentalnymi uzyskanymi na drodze pomiaru termoparą naturalną. Otrzymano akceptowalną dokładność średniej oraz maksymalnej temperatury kontaktu, potwierdzając tym samym poprawność modeli symulacyjnych.
The paper concerns heat propagation while orthogonal cutting of C45 steel by means of the carbide cutting tool without protective coating. In the model tests, the modified finite difference method was applied for determination of changes of temperature distribution, the mean and maximum contact temperatures. The tests concerned changes of temperature distribution in the cutting zone, resulting from different shape configurations of the heat flux generated on the shear plane and at the contact length between the chip and the tool rake face. Simulations of heat propagation were based on the simplified model of the heat flow assuming linear heat sources of variable intensity along its whole length. The results of simulations were compared with the data from literature and experimental data obtained from measurements by means of natural thermocouple. Acceptable accuracy of the mean and maximum contact temperature was obtained, so correctness of the simulation models was proved.

In this work, the influence of the crack propagation velocity on heat release in blade was shown. Research was be performed during fatigue test of the compressor blade. In the investigations, the blade with the V-notch was examined. The blades during experiment were entered into transverse vibration by a vibration system Unholtz-Dickie UDCO-TA-250. The crack propagation process was conducted in resonance condition. The blades were periodically bended what simulates geometry changes during operation of the engine. The main part of the work is based on research of fatigue. During investigations both the amplitude of the crack length and also the blade tip displacement were controlled. Additional velocity of crack propagation was measured by change of a crack length in time. In the same time temperature, distribution pictures were observed. The taken picture was used to exhibit the phenomenon and shown the heat propagation direction. The main results of presented investigation are both the parameters of a crack and the crack growth dynamics in the compressor blade subjected to vibrations. An additional original result of the work is connection between velocity of crack propagation and temperature distribution taken from picture. The result of above analysis can be used in determining the amount of energy released during the cracking process and evaluate the amount of energy required for the growth of a gap. In this work, the capabilities of the proposed method and the problems associated with it were defined. The results presented in this paper have theoretical and practical value.

Opis:
One of the main parameters affecting the hydrodynamic lubrication of slide bearings is the viscosity of lubricating oil. Many studies show, that significant changes in the viscosity of oil occur along with changes in its temperature. The influence on the temperature distribution in the lubrication gap of the slide bearing have a variety of factors, and one of them is the amount of heat exchanged between the lubricant and the environment. The temperature of the lubricating oil of operating bearing is usually higher than the ambient temperature. In addition to the convection, which occurs during the flow (heat exchange related to the oil supply and discharge system) some amount of heat is transferred to the bearing sleeve material (and also to the bearing shaft), and then it is conducted to sleeve outer surface. The amount of heat transferred through the bearing sleeve is mainly dependent on the difference of temperatures between inner and outer sleeve surfaces and also depend on the heat conduction coefficient of sleeve material. This article presents the results of modelling of the influence of amount of heat conducted through the bearing material, on the hydrodynamic lubrication of a conical slide bearing. The study concerned various values of the heat conduction coefficient of the bearing material to investigate its influence on the temperature values of lubricating oil, and thus, on its viscosity, on the distribution of hydrodynamic pressure and on the calculated values of bearing load carrying capacities and friction forces.

Opis:
The aim of this work is to investigate, how in the adopted model of hydrodynamic lubrication of a conical slide bearing, the change of the heat flux value at the bearing shaft, affects bearing operating parameters. In this research, the authors use, the known from the literature, Reynolds type equation, describing the stationary hydrodynamic lubrication process of a conical slide bearing. The analytical, solutions, that determine the components of the lubricating oil velocity vector and the equation (analytical solution of energy equation) determining the threedimensional temperature distribution in the lubrication gap, was also adopted from previous works. In order to obtain numerical solutions, the Newton’s method was used, and the derivatives in the Reynolds type equation were approximated by the finite differences. An application of the method of subsequent approximations allowed considering the influence of temperature, pressure and shearing rate on the viscosity of lubricating oil. The considerations were performed by adopting the Reynolds condition of the hydrodynamic oil film. It was tested, how the assumed value of the heat flux on the bearing shaft surface affects the values of the obtained operating parameters, i.e. the transverse and longitudinal component of the load carrying capacity, friction force and coefficient of friction.

Opis:
It is well known that the most effective method of air distribution in high-heat areas is displacement ventilation with a variable air loss according to changeable operating conditions. Dense equipment arrangement makes requirements to air distribution even higher. The necessity of spreading jets till they reach convective flows is shown. To slow down these jets uniform air supply is required at the exit of an air distributor. Modern devices do not fully meet this requirement. The suggested method of air supply ensures uniform air distribution and thorough ventilation of the area at a changed expenditure of inflowing air.
Wiadomo, że najbardziej skutecznym sposobem nawiewu powietrza do pomieszczeń ze źródłami ciepła jest wentylacja wyciągowa ze zmiennym przepływem powietrza w zmiennych warunkach eksploatacyjnych. Zwiększanie szczelności pomieszczeń podwyższa wymagania do nawiewu powietrza. Aby zmniejszyć prędkość strumieni, należy zapewnić równomierny przepływ powietrza na wyjściu z jednostki nawiewu powietrza. Stosowane metody wentylacji na ogół nie spełniają tego wymogu. Zaproponowany sposób dopływu powietrza pozwala zapewnić równomierność dostarczania powietrza i likwidację nieprzewietrzanych stref przy zmianie wydatku przepływu powietrza.

Opis:
Maintaining railway turnout operability is crucial for ensuring railway transport safety. Electric heating of railway turnouts is a significant technical and economic issue. The classical heating is characterised by high power consumption. For this reason, research is needed to optimise the current system. This paper presents results of a numerical analysis and of experimental researches. The numerical analysis was carried out using the ANSYS software. There was conducted a numerical comparative analysis of energy loss during heating performed using two different heaters. Including the classical method and a heater thermally insulated from a rail. In the first step, heating of a working space filled with a substitute snow model was considered. The snow-covered surface area was held within the working space of the turnout. It was assumed that the snow substitute material had thermal properties approximately the same as real light snow. It was also assumed that the material is in the solid state which would not undergo a phase change. In the next step, a real snow model that included the phase change process was taken into account. The energy efficiency and heat distribution in the turnout have been analysed and compared. The experimental researches were carried out in a physical model. The results showed that the use of a contactless heater results in creating a larger area over which emitted heat affected snow in the working space. Consequently, more snow was melted around the contactless heater than the classic one. This experimental observation supported the results of the numerical analyses presented previously.

Opis:
Thermal and time delay aspects of long interconnect lines have been investigated. To design a modern integrated circuit we need to focus on very long global interconnects in order to achieve the desired frequency and signal synchronization. The long interconnection lines introduce significant time delays and heat generation in the driver transistors. Introducing buffers helps to spread the heat production more homogenously along the line but consumes extra power and chip area. To ensure the functionality of the circuit, it is compulsory to give priority to the time delay aspect and then the optimized solution is found by making the power dissipation as homogenous as possible and consequently the temperature distribution T (relative to ambient) as low as possible. The technology used for simulations is 65 nm node. The occurring phenomena have been described in a quantitative and qualitative way.
