Impact of double-stratification on convective flow of a non-Newtonian liquid in a Riga plate with Cattaneo-Christov double-flux and thermal radiation

Abstract

The intention of the paper is to find the outcome of thermal radiation of a second grade fluid over a Riga plate with Cattaneo-Christov (CC) double flux and double stratification’s. The governing mathematical models are changed into an ordinary differential equations (ODE) using suitable transformations. These resultant models are analytically solved with homotopy analysis method. The impact of pertinent parameters on velocity distribution, temperature distribution, concentration distribution, skin friction coefficient, local Nusselt number and local Sherwood number is analyzed graphically. We found that the skin friction coefficient suppresses with enhancing the injection/suction parameter. The energy transfer gradient suppresses with rising the thermal stratification parameter. Also, we found that the mass transfer gradient decreases with increasing the solutal stratification parameter.
