A shear flow investigation for incompressible second grade nanomaterial: Derivation and analytical solution of model

摘要

A theoretical study of entropy generation (EG) has been conducted in flow of second grade nanomaterial in the presence of Darcy Forhheimer porous space. MHD stagnation point flow with nonlinear mixed convection is examined. Joule heating, nonlinear radiation, Brownian diffusion, dissipation and thermophoresis effects are accounted in the modeling of energy expression. Entropy rate is calculated. The chemical reaction is considered for mass transport with activation energy is addressed. The nonlinear flow expressions are analytical tackled for series development via homotopy method. Flow parameters are graphically discussed. Skin friction and Nusselt number are graphically interpreted and discussed. The obtained outcomes addressed that the velocity decreases against magnetic variable. Thermal field and layer thickness growths via radiation and Eckert number. Key observations are listed.
