Three Dimensional Visco-Elastic Flow with Heat and Mass Transfer Past a Vertical Porous Plate in Presence of Variable Suction
Authors: ,
Abstract: An analysis is carried out to study the unsteady three -dimensional flow of a visco-elastic fluid past a vertical porous plate in presence of variable suction .The effects of heat and mass transfer are taken into account .The fluid is characterized by Rivlin-Ericksen second - order fluid model .The analytical expressions for the velocity ,temperature and species concentration have been obtained .The non -dimensional shearing stress, rate of heat transfer in terms of Nusselt number and the rate of mass transfer in terms of Sherwood number at the plate have been demonstrated graphically in possible cases. It is found that the flow field is significantly affected by the visco-elastic parameter in combination with other flow parameters.
