Thermal-diffusion and diffusion-thermo effects on MHD flow of viscous fluid between expanding or contracting rotating porous disks with viscous dissipation

An analysis is performed to study the effects of mass transfer and chemical reaction on laminar flow in a porous channel with moving or stationary walls. The governing equations are reduced to non-linear ordinary differential equations based on the physics of the flow. An analytical approach, namely, the homotopy analysis method (HAM) is applied in order to obtain the solutions of the ordinary differential equations. The convergence of the obtained series solutions is analyzed. The effects of various parameters on flow variables have been discussed. Comparisons of the HAM solutions with the numerical solutions using shooting method coupled with Runge-Kutta scheme are in excellent agreement. © 2013 Elsevier Ltd.

Flow and mass transfer effects on viscous fluid in a porous channel with moving/stationary walls in presence of chemical reaction

The present study investigates the thermal-diffusion and diffusion-thermo effects of a viscous fluid in a two-dimensional channel between slowly expanding or contracting walls with weak permeability. Assuming symmetric injection or suction along the uniformly expanding porous walls and using similarity transformation, the governing flow equations are reduced to nonlinear ordinary differential equations. The resulting equations are then solved analytically using a perturbation technique in permeation Reynolds number and wall dilation ratio. The effects of various physical parameters on flow variables have been discussed numerically and explained graphically. © 2012 Elsevier Ltd. All rights reserved.
