“…The computations of U, V and T at time level (k + 1) using the values at previous time level (k) are carried out as follows: the finite difference Eq. (14) at every internal nodal point on a particular i-level constitute a tridiagonal system of equations. Such a system of equations are solved by Thomas algorithm as described in Carnahan et al [22].…”

“…The effect of thermal radiation on the natural convection flow along a uniformly heated vertical porous plate with variable viscosity and uniform suction velocity were investigated numerically by Anwar Hossain et al [13]. Elbashbesy and Dimian [14] investigated numerically the effect of radiation on flow of an optically dense viscous fluid and heat transfer over an isothermal wedge in this paper. Seddeek [15] studied the effects of radiation and variable viscosity on a MHD free convection flow past a semi-infinite flat plate with an aligned magnetic field in the case of unsteady flow.…”

Free convection over an isothermal vertical plate immersed in a fluid with variable viscosity and thermal conductivity is studied in this paper. We consider the two-dimensional, laminar and unsteady boundary layer equations. Using the appropriate variables, the basic governing equations are transformed to non-dimensional governing equations. These equations are then solved numerically using a very efficient implicit finite difference scheme known as Crank-Nicolson scheme. The fluid considered in this study is of viscous incompressible fluid of temperature dependent viscosity and thermal conductivity. The effect of varying viscosity and thermal conductivity on velocity, temperature, shear stress and heat transfer rate are discussed. The velocity and temperature profiles are compared with previously published works and are found to be in good agreement.

“…Many processes in engineering occur at high temperatures and the full understanding of the effect of radiation on the rate of heat transfer is necessary in the design of equipment. The effect of radiation on the boundary layer flow was studied by Elbashbeshy and Dimian [6], Hossain et al [7], Bataller [8] and Cortell [9 ]. The radiation effect is considered by Bataller [8] in the study of boundary layer flow over a static flat plate (Blasius flow) andCortell [10] In the present study, heat and mass transfer in MHD Nano fluid over a nonlinear stretching sheet in presence of suction/injection have been investigated.…”

Abstract-The present paper is to investigate the combined effects of the heat and mass transfer on the unsteady twodimensional boundary layer flow over a nonlinear stretching sheet in the presence of Stagnation point and Suction/ Injection.The governing nonlinear partial differential equations have been reduced to the coupled nonlinear ordinary differential equations by the similarity transformations. The resulting equations are solved numerically by using Keller box method. The velocity, temperature and concentration distributions are discussed numerically and presented through graphs.

We study the boundary layer characteristics of heat and mass transfer flow past a vertical wedge in the presence of thermal radiation. The surface temperature and the species concentration are assumed to be oscillating in the magnitude but not in the direction of oncoming flow velocity. The governing equations have been solved by two distinct methods, namely, the straightforward finite difference method for the entire frequency range, and the series solution for the low frequency range and the asymptotic series expansion method for the high frequency range. Numerical solutions have been presented in terms of the amplitudes and phase angles of the skin friction, the rate of heat transfer and the mass transfer with the variations of Richardson's number, the Prandtl number, the conduction-radiation parameter, the surface temperature parameter and the Schmidt number. Furthermore, the effects of these parameters are examined in terms of the transient skin friction, heat transfer and mass transfer.
