Numerical Modeling Of Boundary Layer Flows With Fludid Particle Suspension

Abstract

ABSTRACT newlineDusty fluid is a continuous fluid medium where a large numbers of very small solid particles are dispersed. Analysis of particle laden buoyancy induced boundary layer dusty fluid flow and heat transfer is a common and challenging problem in chemical engineering, aircrafts structures, environmental fluid mechanics and applied mathematics communities. Examples are widely found in areas like chemical and coating industries, petroleum reservoirs, chemical reactors, geothermal reservoirs, disposal of waste water, energy storage system, printing technology and many others. Though the existence of dust particles may deteriorate the function of machines and appliances, but it maintains the control of fluid flow and heat transfer. Inspired by the numerous impact of dust particles on fluid flow problems in a broad area of science and engineering (especially electrification and heat transfer processes), we are motivated to carry out investigations in the area of dusty fluid flow and heat transfer considering different aspects of the problem. newlineBased on the literature available, radiation effect in a flow of thermal boundary layer is restricted to very limited study past over a stretching surface. In most of the above studies, the effect of radiation and viscous dissipation are considered in the thermal fluid phase only, i.e. in all most all the cases, investigators have claimed that only fluid phase is effected by thermal radiation and viscous dissipation, not the dusty phase. Hence, in this analysis, we develop a balanced mathematical model by including these factors for both the phases and show the corresponding effects
