The Study of Convective Flows and Heat and or Mass Transfer in a Vertical Slot with Combined Driving Force

Abstract

The thesis deals with the investigation of double-diffusive convection in a tilted rectangular enclosure in a single or co-existing layer with the existence of a transverse magnetic field and/or by applying thermal radiation and/or the boundary bounded by porous lining. Natural convection that occurs due to the joined effect of concentration and temperature buoyancy is focused analytically along vertical sides with uniform mass and heat in a slanted tall rectangular enclosure are investigated. And the position of BJ is employed at the porous fluid interface. The analytical part holds for the boundary layer system where the transfer rate of mass and heat are constrained by convection. An Oseen linearized technique is for a long rectangular enclosure loaded with a combined characterized by the Lewis number Le which is correspondent to arbitrary buoyancy ratio. The impact of the tendency angle of various Rayleigh numbers, slip parameter N, Chandrasekhar number Q and radiation parameter R, the concentration, velocity, temperature distribution, Nusselt, and Sherwood numbers are determined and graphically drawn. The impact of Le is recorded by an equality arrangement legitimate for Lewis number in heat transfer driven flow, and short of what one for Le in mass transfer driven flow. The solutions are estimated for distinct values of the inclination angle and#8709; and buoyancy ratio n, slip parameter N, Chandrasekhar number Q, radiation parameter R. The results are associated with the finite cases of the angle and#12310; 90and#12311;^°. newline
