Opis:
This article shows the mathematical method to determine the lateral stress on the shaft and toe resistance of pile using the new approach. The method was originally invented by Meyer and Kowalow for the static load test. The approximation curve was used for the estimation of both settlement curve and toe resistance curve of the pile. The load applied at the head of the pile is balanced by the sum of two components: the resistance under the toe of the pile and the skin friction. Therefore, the settlement curve is compilation of two factors: the skin friction curve and the resistance under toe curve. The analysis was based on the verification of the methods using laboratory experiments, that is, static load tests. The results of the research allowed to determine the relationship between parameters of the Meyer-Kowalow curve. On the basis of the relationships, it was possible to determine the skin friction and the toe resistance of the pile. Mathematical analysis of curve parameters allowed to determine the influence of the toe resistance on the settlement.

Opis:
This paper reports some results of turbulent boundary layer computation. The calculation is made assuming that law of the wall is valid throughout the boundary layer. Simple relations are proposed for friction for a smooth pipe and a flat plate at zero incidence. The results are compared with recent measurements. Encouraging results are obtained for both the cases of flows.

Opis:
An arithmetical methodology is used to study natural convection with properties of pressure work over a semi-infinite vertical oscillating cylinder. The governing partial differential equations are set up and the resulting equations are changed into a non-dimensional form using the proper non-dimensional quantities. The set of non-dimensional partial differential equations is solved arithmetically using a well-organized method known as the Crank-Nicolson method. The velocity, as well as temperature profiles for different values of parameters are studied with the assistance of graphs.

Opis:
Transfer of axial force from the head of a pile to the surrounding soil by skin friction and toe resistance is still uncertain. The results of the static pile load test are usually presented as settlement curve. This curve can be divided into two components: skin friction curve and toe resistance curve according to the settlement. Laboratory research of pile load test was carried out in two schemes: with skin friction and without skin friction. The study proved that the toe resistance with and without skin friction is not the same. Skin friction influence on toe resistance due to settlement. This phenomenon is not usually taken into account, but very often has a significant impact on axially applied load transfer. In the paper results of laboratory pile load tests id, different schemes were presented.
Przekazywanie pionowej siły osiowej przyłożonej w głowicy pala na otaczające podłoże gruntowe jest zagadnieniem wciąż nierozwiązanym i w wielu przypadkach budzącym wiele wątpliwości. Wynik próbnego obciążenia statycznego są zwykle przedstawiane na wykresie w postaci krzywej osiadania pala. Krzywa osiadania może być podzielona na dwie składowe krzywe: krzywą oporu pobocznicy i krzywą oporu podstawy pala w stosunku do osiadania głowicy pala. Badania laboratoryjne próbnych obciążeń statycznych zostały przeprowadzone na palach modelowych, w dwóch schematach obciążenia: z udziałem pobocznicy i bez udziału pobocznicy w przekazywaniu obciążenia przyłożonego w głowicy pala. Wyniki badań wskazują, że opór podstawy pala jest różny w zależności od schematu. W związku z tym istnieje zależność oporu podstawy i pobocznicy pala. W artykule przedstawiono wyniki badań laboratoryjnych wraz z interpretacją.

Opis:
This paper expands the M-K curve theory with examples of the most commonly mentioned pile-soil mechanics behaviours in the literature and their corresponding κ 2 variations. A brief introduction shows the history of the Meyer-Kowalow theory and its basic assumptions. This is followed by the relationship between in situ investigation CPT results, with parameters C1, C2, Ct used to approximate the load-settlement curve according to the M-K theory. The Meyer-Kowalow curve satisfies asymptotic behaviour for small loads, where linear theory applies, and for limit loads, when pile displacement is out of control. Essential in the description are constant parameters C, which refer to the aggregated Winklers modulus, Ngr limit loads and k, which is crucial for static load test results. For this reason, the authors sought to calculate the κ value based upon soil mechanics principles. This article shows methods for checking statistical mathematical calculations, published earlier by Meyer using CPT investigations. It presents real case calculations and directions for future planned research.

Opis:
A boundary layer flow of an electrically conducting viscous fluid past a converging channel in the presence of thermophoresis, heat source, chemical reaction, viscous dissipation and simultaneous heat and mass transfer characteristics is studied in the paper. An external magnetic field of uniform strength is applied transversely to the channel. The similarity solution has been used to transform the partial differential equations that represent the problem into a boundary value problem of coupled ordinary differential equations, which in turn are solved numerically using MATLAB’s built in solver bvp4c. Numerical computations are carried out to solve the problem and graphical illustrations are made to get the physical insight of the same. The convergent channel flow problem of an incompressible electrically conducting viscous fluid in the presence of a magnetic field has a wide range of applicability in different areas of engineering, specially in industrial metal casting and control of molten metal flow.

An MHD fluid flow is examined over a vertical plate in the presence of Dufour and Soret effects. The resulting momentum, energy and concentration equations are then made similar by introducing the usual similarity transformations. These similar equations are then solved numerically using the Runge-Kutta fourth order method with shooting technique. The effects of various parameters on the dimensionless velocity, temperature and concentration profiles as well as the local values of the skin-friction coefficient, the Nusselt number and Sherwood number are displayed graphically and in a tabular form. A comparison with previously published work is obtained and an excellent agreement is found.

A numerical solution of a transient natural convection flow past a semi-infinite inclined plate under the combined buoyancy effects of heat and mass transfer along with chemical reaction is presented herewith. The governing boundary layer equations for the above flow problem for a first order homogeneous chemical reaction are set up and non-dimensionalised. An implicit finite difference method is employed to solve the unsteady, nonlinear, integro and coupled partial differential equation. Numerical results are presented for various parameters occurring in the problem. The unsteady velocity, temperature and concentration profiles, local and average skin friction, Nusselt number and Sherwood number are studied for both a generative and destructive reaction.

Opis:
An unsteady boundary layer free convective flow and heat transfer of a viscous incompressible, microploar fluid over a vertical stretching sheet is investigated. The stretching velocity is assumed to vary linearly with the distance along the sheet. Two equal and opposite forces are impulsively applied along the x-axis so that the sheet is stretched, keeping the origin fixed in the micropolar fluid. The transformed highly non-linear boundary layer equations are solved numerically by an implicit finite difference scheme for the transient, state from the initial to the final steady-state. To validate the numerical method, comparisons are made with the available results in the literature for some special cases and the results are found to be in good agreement. The obtained numerical results are analyzed graphically for the velocity, the microrotation, and the temperature distribution; whereas the skin friction, the couple stress coefficient and the Nusselt number are tabulated for different values of the pertinent parameters. Results exhibit a drag reduction and an increase in the surface heat transfer rate in the micropolar fluid flow compared to the Newtonian fluid flow.

The aim of the paper is to investigate an oscillatory fluid flow and heat transfer through a porous medium between parallel plates in the presence of an inclined magnetic field, radiative heat flux and heat source. It is assumed that electrical conductivity of the fluid is small and the electromagnetic force produced is very small. The governing coupled equations of motion and energy are solved analytically. Numerical results for the velocity and temperature profiles, local skin friction coefficient and local Nusselt number for various values of physical parameters are discussed numerically and presented graphically.

Opis:
This paper studies the mathematical implications of the two dimensional viscous steady laminar combined free-forced convective flow of an incompressible fluid over a semi infinite fixed vertical porous plate embedded in a porous medium. It is assumed that the left surface of the plate is heated by convection from a hot fluid which is at a temperature higher than the temperature of the fluid on the right surface of the vertical plate. To achieve numerical consistency for the problem under consideration, the governing non linear partial differential equations are first transformed into a system of ordinary differential equations using a similarity variable and then solved numerically under conditions admitting similarity solutions. The effects of the physical parameters of both the incompressible fluid and the vertical plate on the dimensionless velocity and temperature profiles are studied and analysed and the results are depicted both graphically and in a tabular form. Finally, algebraic expressions and the numerical values are obtained for the local skin-friction coefficient and the local Nusselt number.

Opis:
In the present paper, a viscoelastic boundary layer flow and heat transfer over an exponentially stretching continuous sheet in the presence of a heat source/sink has been examined. Loss of energy due to viscous dissipation of the non-Newtonian fluid has been taken into account in this study. Approximate analytical local similar solutions of the highly non-linear momentum equation are obtained for velocity distribution by transforming the equation into Riccati-type and then solving this sequentially. Accuracy of the zero-order analytical solutions for the stream function and velocity are verified by numerical solutions obtained by employing the Runge-Kutta fourth order method involving shooting. Similarity solutions of the temperature equation for non-isothermal boundary conditions are obtained in the form of confluent hypergeometric functions. The effect of various physical parameters on the local skin-friction coefficient and heat transfer characteristics are discussed in detail. It is seen that the rate of heat transfer from the stretching sheet to the fluid can be controlled by suitably choosing the values of the Prandtl number Pr and local Eckert number E, local viscioelastic parameter k1 and local heat source/ sink parameter β.

Opis:
In this paper are assumed micro-ridges and micro-grooves on the Journal and bearing sleeve surfaces. Friction on the boundary layer of the body moving in the oil at high Reynolds numbers may be decreased due to such asculpturing of the surface. The grooved scale of the shark skin is an example of such tribological systems. There size ranges of the grooves are from 200 jum to 400/jm. The surface of the each scale contains parallel groove between so-called ribbed directed almost parallel to the longitudinal body axis. An explanation of the shark skin effect has been proposed recently for the micro-bearing surfaces shapes execution. In the boundary layer, not only longitudinal micro-turbulence but also cross-directed micro-turbulence occurs. The longitudinal grooves of the shark and bearing surface prevent the appearance of the cross-directed micro-turbulences. Forces of the streaming oil in bearing or micro-bearing gap act on the bearing surface in two different ways. On one side, the oil generates the pressure directed normally to the surface of the Journal surface and is responsible for inertiaforces. On the other side, friction or shearing force acts tangentially to the bearing surface. The resulting force depends on the geometry of the body, its relative dimensions to the oilflow and on such characteristics of the oil as its density, viscosity and velocity.

Opis:
The optimum surface and frictional properties of textiles depend on their specific application. In this study, we examined the frictional behaviour of medical wipes against 15 mechanical near skin equivalents using synthetic leather material and bovine leather. The frictional behaviour characteristics, both static and kinetic, were evaluated at four different normal loads. It was seen that the static and kinetic frictional coefficients decrease with an increasing normal load for all the reference candidates studied. Higher friction was experienced for the movement of the cotton and viscose wipe against leather than that for synthetic polyurethane (PU) and silicone material. The friction of the wipe against any equivalent skin material was found to be dependent on its surface nature and the morphology of the material against which it is in contact and moves. Friction is necessary in real-time use for a wipe to have an inherent frictional resistance for movement against skin during use.

W pracy zbadano właściwości cierne gaz chirurgicznych podczas kontaktu z mechanicznymi odpowiednikami skóry, do badań użyto syntetycznych materiałów skórzanych oraz skórę bydlęcą. Określono statyczne i kinetyczne współczynniki tarcia przy czterech różnych obciążeniach. Zaobserwowano, że oba współczynniki tarcia maleją wraz ze wzrostem obciążenia. W przypadku skóry uzyskano wyższy współczynnik tarcia, niż dla poliuretanu i materiału silikonowego. Stwierdzono, że współczynnik tarcia zależy od charakteru powierzchni i morfologii materiału, z którym styka się gaza.
