Title: Unsteady Oberbeck Convection Through Vertical Stratum
Abstract: The unsteady Oberbeck convection through vertical stratum has been considered for viscous incompressible fluid. The expressions for velocity profile, temperature profile and mass concentration have been obtained. The method which has been employed here is Laplace transform method. The impact of dimensionless parameters like Grashof number, modified Grashof number, Prandtl number, Schmidt number, and Reynolds number has been discussed graphically on velocity field, temperature field, Skin friction and heat transfer rate. Some of major conclusions are given below:
* the viscosity becomes large which resists the diffusion of concentration due to
convection.
* The temperature difference (T0 - T1) controls the convectional heat flow.
* As the value of Prandtl number increases the flow of heat becomes faster. Due to this reason, the
small Prandtl number is not significant in the problems related to heat transfer.
