Influence of thermal dispersion and variable viscosity on mixed convection flow in non-Darcy porous medium filled by nanoliquid

In this current paper, a numerical analysis was performed to study the effects of variable viscosity and thermal dispersion considered for an Ergun-Darcy mixed convection flow on a heated horizontal plate from below by variable heat flux in a saturated porous medium filled with Tiwari and Das nanoliquid. The governing partial differential equations are transformed into coupled nonlinear ordinary differential equations using an appropriate similarity transformation and the resulting system of equations is then solved numerically by efficient finite-difference method. Numerical results are presented to illustrate how the physical parameters affect the flow field, temperature and concentration. Moreover, the interesting features of the solutions in terms of the number of Nusselt are presented graphically.
