Accelerated Non-Coaxial Rotating Flow of MHD Viscous Fluid with Heat and Mass Transfer

Abstract

Abstract An exact analysis on heat and mass transfer of mixed convection MHD viscous fluid flow due to accelerated non-coaxial rotation is analyzed. This analysis is considered through a porous medium. The rotation and buoyancy forces involved in this problem give effects on the fluid motion. Dimensional momentum, energy and concentration equations are presented in partial differential equations with initial and boundary conditions which then are reduced into non-dimensional form by introducing non-dimensional variables. This problem is analytically solved by using Laplace transform method and the exact solution obtained for velocity, temperature and concentration profile are graphically plotted in order to investigate the impact of Grashof number Gr, modified Grashof number Gm, Prandtl number Pr and Schmidt number Sc as well as accelerated, magnetic and porosity parameter on its behavior. The results show that the increasing acceleration parameter raises the velocity profile while increasing of Prandtl number and Schmidt number leads to a fall in velocity profile. A verification of obtained solution is conducted by comparing present results with published results and it was found to be in a good agreement.
