Unsteady incompressible flow and heat transfer of dusty non-ionized fluid with charged suspended particulate matter (spm) between two infinite parallel plates due to the motion of one of them

Abstract

Paper presented at the 8th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Mauritius, 11-13 July, 2011.In the study of transport phenomena, mass, momentum and energy are increasingly recognized of fundamental importance. The prediction of the mechanical transport in the ocean is a difficult task. Parallel flow through a straight channel provides a good understanding in connection with flow in estuaries. Thus to study the transport through estuaries, a simple case of an unsteady incompressible flow and heat transfer of a non-ionized fluid with charged SPM between two infinite parallel plates has been considered. The solutions of the governing equations of flow field have been obtained by using Crank-Nicholson finite difference technique. An illustration of dependence of physical variables on nondimensional parameters viz. diffusion parameter, finite volume fraction, concentration parameter, magnetic parameter has been depicted through figures and tables. The direction of heat transfer has been discussed by taking a situation PrEc   2 in both frozen flow and equilibrium flow regimes. The electrification of particles has an effect on reduction of the velocity of carrier fluid as well as SPM but on increase of the temperature of carrier fluid and SPM.
