Numerical Study on Unsteady Flow and Mass Transfer Past a Vertical Porous Plate with Variable Viscosity

Abstract

Present study is devoted for an unsteady flow mass and heat transfer past a vertical porous plate with variable viscosity. The effects of chemical reaction, heat source and thermal conductivity on the flow are also investigated. The partial differential equations, which are essentially nonlinear in nature, along with specific boundary conditions have been converted to the dimensionless form by using appropriate coordinate transformation. Explicit finite difference method has been applied to solve the dimensionless momentum, concentration and energy equations numerically. The velocity, concentration and temperature outlines have been discussed for well-known parameters whereas Nusselt number and skin friction have been represented in tabular forms. The variations of stream lines and isotherms have also been displayed graphically. Absolute conclusion has finally been drawn based on the numerical and graphical results.

Heat Transfer and Entropy in a Vertical Porous Plate Subjected to Suction Velocity and MHD

“…The variable viscosity can also have some impact on the heat and mass transferred through the porous media. It was noted that the velocity decreased when the viscosity parameter increased [11], which can be attributed to the strong dependence of fluid flow on viscosity. The study of porous media adjacent to the vertical plate has inspired the analysis of different types of fluids.…”
