چکیده
The analysis of mass and heat transfer in magnetohydrodynamic (MHD) flows has significant applications exchangers, cooling nuclear reactors, designing energy systems casting injection processes different types fluids. On the other hand, extraction crude oil, flow human or animal blood, as well polymer fluids liquid crystals are just some examples micropolar fluid flows. Due to broad application spectrum theory flows, significance impact external magnetic field on these fluids, this paper considers stationary a between two plates under influence an which is perpendicular direction flow. Stationary maintained at constant temperatures, while whole problem considered non-inductive approximation. equation system used define physical consideration reduced differential equations that have been solved analytically solutions general nature. In addition for velocity, microrotation temperature, gives shear stress plates, Nusselt number rate. provided applied order reach conclusions about characteristics porous media nature by means chart analysis. General conclusions, obtained result paper, give us opportunity understand highlight their significance.

This analytical investigation examines the magnetohydrodynamic flow problem of an incompressible micropolar fluid between the two eccentrically placed disks. Employing suitable transformations, the flow governing partial differential equations is reduced to ordinary differential equations. An exact solution representing the different flow characteristic of micropolar fluid has been derived by s...

متن کاملCoupling Fluid Flow with Porous Media Flow
The transport of substances back and forth between surface water and groundwater is a very serious problem. We study herein the mathematical model of this setting consisting of the Stokes equations in the fluid region coupled with the Darcy equations in the porous medium, coupled across the interface by the Beavers–Joseph–Saffman conditions. We prove existence of weak solutions and give a compl...

A stable Alternating Direction Implicit finite-difference algorithm is used to model transient fiuid flow in heterogeneous porous media. In connection with the laboratory system for pressure transient testing of core permeability, the effects of permeability heterogeneities on the characteristics of the pressure transient were investigated. The results show that the early portion of the pressur...
