Slip Viscous Flow Over an Exponentially Stretching Porous Sheet with Thermal Convective Boundary Conditions

Abstract

The aim of the paper is to investigate the boundary layer flow, heat and mass transfer towards the exponentially stretching sheet in a viscous fluid. Similarity transformations are used to convert non-linear governing equations of the flow into non-linear ordinary differential equations. The successive linearization method is used to linearize the resulting ordinary differential equations and then solved by Chebyshev spectral collocation method. A quantitative analysis is made with the previously published results for special cases. The numerical results for the physical parameters on the development of the flow, temperature, concentration, skin friction coefficient, heat and mass transfer are given. It can be concluded from the present analysis that an increase in slip parameter decreases the velocity and increases the temperature and concentration. The heat transfer coefficient is increasing and the velocity, temeperature and concentration are decreasing with the increase in the suction parameter. The temperature and heat transfer coefficient are increasing with the increase in the Biot number.
