Numerical and Analytical Investigation for Darcy-Forchheimer Flow of a Williamson Fluid over a Riga Plate with Double Stratification and Cattaneo-Christov Dual Flux

The Darcy-Forchheimer flow of a Williamson fluid over Riga plate was analyzed in this paper. Energy and mass equations are modeled with Cattaneo-Christov theory double stratifications. governing PDE models altered into ODE models. These numerically solved by MATLAB bvp4c analytically the homotopy analysis method. impact parameters on velocity, temperature, concentration, skin-friction coefficient, local Nusselt number, Sherwood number is scrutinized via graphs tables. We acknowledged that speed becomes diminishes for more presence porosity parameter. Also, we noted thermal solutal boundary layer thicknesses waning due to their corresponding stratification parameters. In addition, maximum decreasing percentage skin friction obtained when suction/injection parameter varies from 0.0 0.4 viscous fluids. increasing occurs 0.8
