The motion of the viscous, incompressible fluid through a porous medium with heat and mass transfer over a shrinking sheet is investigated. The cross-diffusion effect between temperature and concentration is considered. This phenomenon is modulated mathematically by a set of partial differential equations which govern the continuity, momentum, heat, and mass. These equations are transformed to ...

In this paper thermophoretic particle deposition on an unsteady magnetodydrodynamic (MHD) free convective heat and mass transfer flow along an impulsively started infinite inclined porous plate under the influence of Dufour-Soret effects have been studied numerically. The transformed governing equations obtained by similarity transformations are solved by shooting method. Comparison with previo...

This study focused on free convective MHD Casson fluid flow past a permeable vertical plate with microorganisms and Soret-Dufour mechanisms. The physical model is governed by system of partial differential equations (PDEs). set PDEs were overhaul into nonlinear ordinary equation considering acceptable similarity variable. spectral relaxation method (SRM) was utilized to obtain solution the equa...

A study on heat and mass transfer behaviour on an anisotropic porous medium embedded in square cavity/annulus is conducted using Incompressibe Smoothed Particle Hydrodynamics (ISPH) method. In the case of square cavity, the left wall has hot temperature Th and mass Ch and the right wall has cool temperature Tc and mass Cc and both of the top and bottom walls are adiabatic. While in the case of ...

This research deals with the mathematical model for development of peristaltic principle combination pressure and electroosmotic flow (EOF) ionic liquid across microchannels electrokinetic effects. For thermomechanical dynamics, convective conditions on boundary mass heat transfer at walls channel are quantified. microchannel, a porous structure is presumed. Soret, Dufour, Joule heating also li...
