Impact of dissipative heat and radiative heat on MHD viscous flow through a slandering stretching sheet with temperature-dependent variable viscosity

The purpose of the current investigation is to discuss the varying physical properties, that is, thermal conductivity and viscosity of a viscous time-independent flow past a slandering stretching surface. The heat transfer phenomenon is enhanced by the inclusion of an external heat source under the action of dissipative heat energy and thermal radiation. The implementation of convective boundary conditions affects the heat and solutal transfer phenomena with the inclusion of chemical reactions. The flow characteristic is directed by the system of differential equations that are converted to nonlinear ordinary type by appropriate assumptions of similarity variables and stream function. Furthermore, the “homotopy analysis method” is deployed to simplify the system. The convergence of the methodology is also discussed with their various order of approximations. The conformity of the solution is presented along with validation in tabular form. Moreover, the effect of the parameters on flow profiles is explained graphically, and the major contribution of few important parameters is laid down. The rate of shear stress along with the longitudinal velocity profile augments with the enhanced variable viscosity. Furthermore, the reverse impact is rendered for the augmented values of the variable viscosity.
