The MHD oscillatory flow of two immiscible, viscous liquids in a porous channel with heat transfer is the subject this investigation. liquid layers different viscosities both regions. analytical expressions for velocity and temperature distribution have been derived by solving governing equations using regular perturbation method. effects various parameters on velocity, temperature, Nusselt num...

ess as: N a Eng. J and hosti 013.10.0 Abstract In this article, we studied MHD peristaltic flow of a Carreau nanofluid in an asymmetric channel. The flow development is carried out in a wave frame of reference moving with velocity of the wave c1. The governing nonlinear partial differential equations are transformed into a system of coupled nonlinear ordinary differential equations using simila...

This article presented an analysis of the pulsatile flow non-Newtonian micropolar (MP) fluid under Lorentz force’s effect in a channel with symmetrical constrictions on walls. The governing equations were first converted into vorticity–stream function form, and finite difference-based solver was used to solve it numerically Cartesian grid. impacts different controlling parameters, including Har...

a numerical model is developed to simulate the transport phenomena in the flow channel between parallel plates with porous and non-porous (or impermeable) walls. the continuity and momentum equations were solved first, assuming the wall reynolds number in the range of with the suction or injection of air at a speed equal to the uniform inlet velocity. the results show that at constant inlet and...

a finite volume-lattice boltzmann algorithm is applied to study skin friction behaviour in different channel flows. for this purpose, cell centred scheme is adapted to discretize the boltzmann equation and consistent boundary conditions are also addressed, which resulted in a wider domain of stability. a simulation of flow in a two dimensional channels with different geometries are carried out....

It is proved that irrespective of compressibility tokamak steady states with purely poloidal mass flow can not exist in the framework of either magnetohydrodynamics (MHD) or Hall MHD models. Non-existence persists within single fluid plasma models with pressure anisotropy and incompressible flows.
