Abstract

The present study concentrates on the analysis of MHD free convection flow past an inclined stretching sheet. The viscous dissipation and radiation effects are assumed in the heat equation. Approximation solutions have been derived for velocity, temperature, concentration, Nusselt number, skin friction and Sherwood number using Nachtsheim-Swigert shooting iteration technique along with the six-order Runge-Kutta iteration scheme. Graphs are plotted to find out the characteristics of different physical parameters. The variations of physical parameters on skin friction coefficient, Nusselt number and Sherwood number are displayed via table.

Summary

Introduction

Considerable interest has been shown in investigating radiation interaction with natural convection flow commonly known as free convection for heat transfer in fluid. This is due to the significant role of thermal radiation in the surface heat transfer when convection heat transfer is small in free convection problems. Hossain and Takhar [2] analyzed the effect of radiation effects on free convection flow of a gas past a semi infinite flat plate using the Cogley-Vincnitine-Giles equilibrium model. Following Ali et al, Mansour [4] studied the interaction of mixed convection with thermal radiation in laminar boundary layer flow over a horizontal, continuous moving sheet with suction/injection. Chen [7] investigated natural convection flow over a permeable surface with variable wall temperature and concentration
