Abstract

This article numerically studies the influence of Buoyancy effects and thermal radiation of the nonlinear MHD flow with heat and mass transfer characteristics of an incompressible, viscous, electrically conducting and Boussinesq fluid along a permeable vertical stretching sheet. A magnetic field is applied transversely to the direction of the flow. The basic equations governing the flow, heat transfer, and concentration are reduced to a set of non linear ordinary differential equations by using appropriate similarity transformation. The non linear ordinary differential equations are first linearised using Quasi-linearization and solved numerically by an implicit finite difference scheme. Then the system of algebraic equations is solved by using Gauss-Seidal iterative method. The effects of physical parameters on the velocity, temperature, and concentration profiles are illustrated graphically. Velocity, Temperature and Concentration profiles drawn for different controlling parameters reveal that the flow field is influenced appreciably by the presence of buoyancy effects, thermal radiation, and magnetic field.
