Abstract

This study reflects the combined impact of double dispersion and injection/suction on mixed convection flow over a vertical cone in an incompressible viscous fluid-saturated porous medium. The governing equations of the model are non-dimensionalized throughout the appropriate transformations and received non-similarity equations are solved numerically via bivariate Chebyshev spectral collocation quasi-linearization method. Computations are reported here graphically to analyze the impact of governing parameters at the different stream-wise locations on the velocity, temperatures, and concentration profiles, like Prandtl number, Schmidt number, buoyancy parameter, injection and suction parameter, thermal dispersion, and Solutal dispersion parameters. Skin friction, heat, and mass transfer rates are also reported in graphical and tabular form. To establish the efficiency of the adopted numerical technique, we have made a comparison with the earlier published results and found them to be of great consent. The residual analysis study also illustrated, which proves the convergence of the present results.
