Abstract
The contribution of viscosity is quite dynamical and important in different industrial and engineering processes where the thermal management system is based on fluid flows. For such transportation processes, the thermal system is highly fluctuated with variation of viscosities. It is commonly noticed that in most of recent in-vestigations, the contribution of viscosity is assumed to be constant. Owing to importance of variable viscosity, this communication highlights the role of variable viscosity regarding the slip flow of Maxwell fluid in bidi-rectional moving porous space. In order to generalize the problem, the applications of thermal radiation, external heating source and magnetic force are considered. Moreover, the evaluation of heat transfer is further supported with viscous dissipation. The variable on set of thermal conductivity and viscosity are predicted via Reynolds viscosity model. The model of a nonlinear system with appropriate boundary conditions is transformed to nonlinear differential system. The Runge-Kutta (RK-4) numerical scheme is followed to presenting the approx-imate simulations. A parametric examination of determined parameters is carried out. The graphical results of chemical reactions are also brought into discussion. A fall in transverse velocity component due to interaction of slip is noted. It is summarized that variable viscosity of fluids is more effective to enhance the thermal mechanism.
