MHD stagnation point flow accounting variable thickness and slip conditions

Abstract

This communication addresses the second-order velocity and thermal slip features in magnetohydrodynamic (MHD) stagnation point flow past a stretching sheet with variable thickness. Energy expression in presence of dissipation and thermal radiation are examined. A comparative study with first-order velocity and thermal slip condition is analyzed. Analytical solutions of the resulting systems are obtained by homotopy analysis method. Plots for important variables in the flow quantities are made and discussed. It is observed that velocity of fluid increases for higher estimation of velocity power index while it decreases for wall thickness parameter. Surface drag force and heat transfer rate are decreased for larger wall thickness and Prandtl number. Present computations are consistent with those of existing studies in limiting sense.
