Mixed convection flow over a vertical cone saturated porous medium with double dispersion effect

The objective of this study is to examine the influence of double dispersion on mixed convection flow over a vertical cone of an incompressible viscous fluid saturated porous medium . The mathematical model of the problem is designed in forms of governing equations and the non-dimensionalization is performed via appropriate transformations, to employ the numerical technique; the obtained non-similarity equations are solved numerically by the bivariate Chebyshev spectral collocation quasi-linearization method. The outcomes are reflected graphically and numerically for variation of the governing parameters Prandtl number, Schmidt number, buoyancy parameter, thermal and Solutal dispersion parameters on the velocity, temperature, and concentration profiles at the various stream wise locations, respectively. Further, skin friction, heat, and mass transfer coefficients are also reflected. To authenticate the accuracy of the present computations, we have enclosed a comparison with a prior published results and it found in great consent. The residual analysis study is also pictured in the results and discussion section, which reflects the convergence and stability of the present computations. (C) 2022 Elsevier Inc.
