Analysis Of Mhd Heat And Mass Transfer Flows Of Some Newtonian And Non newtonian Fluids

Abstract

Research on heat and mass transfer in magnetohydrodynamic (MHD) flows plays newlinean important role in many areas of industrial engineering and applied sciences such as newlinemetallurgical manufacturing, several materials processing methods, MHD energy newlineproduction, chemical manufacturing, and synthesis of magnetic liquids. In this newlineresearch work, we mainly work on the effect of MHD on heat and mass transfer flows newlineof some Newtonian or non-Newtonian fluids such as couple stress fluid, Walter s B newlinefluid, and viscoelastic fluid over various geometries such as parallel plates, stretching newlinesheet and rotating cone and disc. Several conditions and effects are incorporated in the newlinefluid model such as variable viscosity, Brownian motion, thermophoresis, heat source, newlineporous medium, thermal radiation, chemical reaction, joule heating, thermal buoyancy newlineforce or nanofluids. The basic governing equations of the flow model are developed newlineaccording to the problem statement and then reduced to non-dimensional form of newlinenonlinear coupled ordinary differential equations using appropriate dimensionless newlineparameters. The obtained dimensionless equations subjected to relevant boundary newlineconditions are solved analytically or numerically using regular perturbation or bvp4c newlinemethods. The behaviour of fluid velocity, temperature and concentration distributions newlinefor different material parameters are visualized and analysed. The rate of heat transfer newlineand coefficient of skin friction are also derived and studied through graphs and tables newline
