FLOW OVER AN EXPONENTIALLY STRETCHING SHEET WITH HALL, THERMAL RADIATION AND CHEMICAL REACTION EFFECTS

Numerical solutions for the boundary layer flow, heat and mass transfer of a viscous incompressible fluid over an exponentially stretching sheet is developed. The effect of Hall current, chemical reaction and thermal radiation are taken into account. Through similarity transformations, the governing boundary layer equations are reduced to a set of coupled non-linear ordinary differential equations and then linearized using the successive linearization method. The resultant linear system is solved using the Chebyshev pseudo spectral method. The numerical results for velocity, temperature and concentration are shown graphically. The skin-frictions are calculated and variations with pertinent parameters are presented in tabular form. Finally, a comparative analysis is conducted between the present results and known results in the literature for the special cases, and are found to be in good agreement.
