Stagnation point radiative flow with Cattaneo-Christov theory and heat generation

Abstract

Heat generation and magnetohydrodynamics for flow of Burgers liquid. Stagnation point flow towards stretched wall is considered. Radiation aspect is nonlinear. Cattaneo-Christov theory and boundary layer approximations are utilized. Related differential systems are formulated. Computations by Optimal homotopy analysis method (OHAM) are implemented. Total residual error is arranged. Graphical illustrations lead to the impacts of sundry parameters. Important points have been concluded. Higher Deborah number lead to velocity enhancement. Decrease in velocity occurs for magnetic field whereas reverse trend witnessed regarding thermal field. Temperature upsurges for higher radiation and heat generation variables. Higher radiation results in Nusselt number enhancement. Mass transport rate enhancement versus Schmidt number is observed. Reduction of thermal distribution occurs for thermal relaxation time.
