Heat and mass transfer effects on the free convection flow of a Visco-Elastic fluid inside a porous vertical channel with soret effect Paikray P.1, Dash S.K.2 1Department of Physics, KPAN College, Bankoi, Khordha, Odisha 2Department of Physics, RIE, Bhubaneswar, Odisha Online published on 4 May, 2019. Abstract This paper deals with heat and mass transfer effects on the free convection flow of a visco-elastic fluid inside a porous vertical channel with Soret effect. Constitutive equations of continuity, motion, energy and concentration are formulated pertaining to the physical situations involved. Such equations are solved after being non-dimensionalised. Graphs and tables are drawn to study the effects of fluid parameters on the flow. It is observed that the non-Newtonian Rc accelerates the flow of the fluid upto certain distance from the lower plate of the channel(0.2<y<0.4). Similar effect is observed for the thermal Grashof number GT. As source strength increases, the temperature rises. But opposite effect is marked in case of the Reynolds number R. Species concentration decreases with the increase of the Schmidt number Sc. Top Keywords Free convection flow, Viscoelastic fluid, Heat and mass transfer, chemical reaction. Top | |
