An implicit-Chebyshev pseudospectral method for the effect of radiation on power-law fluid past a vertical plate immersed in a porous medium

A numerical solution is presented for unsteady coupled heat and mass transfer by natural convection from a non-Newtonian power-law fluid flow past a vertical plate embedded in a non-Darcian porous medium in the presence of viscous dissipation and chemical reaction effects. The governing equations are formulated and a numerical solution is obtained by using an explicit finite-difference scheme. The solutions at each time step have been found to reach the steady state solution properly. The numerical results are presented in tabular and graphical form to show the effects of material parameters of the problem on the solution.

Soret And Dufour Effects

Mixed convection heat and mass transfer along a vertical plate embedded in a power-law fluid saturated Darcy porous medium with Soret and Dufour effects is studied. The governing partial differential equations are transformed into ordinary differential equations using similarity transformations and then solved numerically using shooting method. The effect of Soret and Dufour parameters, power law index and mixed convection parameter on non-dimensional velocity, temperature and concentration fields are discussed. The variation of different parameters on heat and mass transfer rates is presented in tabular form.

Differential Methods

The fluid is actually thought about to be grey, absorbing, and producing yet non-scattering channel. In this study, our team recommend to study the natural convection warmth as well as mass move coming from an upright level embedded in a power-law liquid saturated Darcy permeable resource together with domino effect and radiation effects. The managing partial differential methods are transformed in to ordinary differential formulations using correlation improvements and after that took care of numerically making use of Shooting strategy. It was discovered that speed circulation boosted with improving buoyancy specifications; temp reduced along with enhancing Prandtl amount, and focus minimized along with raising the Schmidt amount.
