An optimal solution of Cattaneo–Christov heat flux model and chemical processes for 3D flow of Eyring–Powell fluid

This paper investigates heat and mass transfer features of Eyring–Powell fluid past a stretching sheet with heterogeneous–homogenous processes. Moreover, investigation of heat conduction is carried out using Cattaneo–Christov heat flux model. With the help of appropriate transformations, the governing partial differential equations are transformed into a set of coupled nonlinear ordinary differential equations. Analytical results are obtained by using the optimal homotopy analysis method. Effects of pertinent physical parameters on thermal and concentration profiles are deliberated through graphical illustrations. We found that temperature profile declines with incrementing the estimations of thermal relaxation parameter. Furthermore, the concentration increases with the augmented estimations of Lewis number.
