The viscous flow equations for the unsteady free convection of a fluid near a doubly infinite vertical plate whose temperature or heat flux is an arbitrary function of time are treated by means of Laplace transforms. Exact solutions are obtained for several typical examples with arbitrary Prandtl number. The results are then generalized to give integral expressions for the velocity and temperature fields due to any prescribed time variation in wall temperature or surface heat flux.

Unsteady Natural Convection

A boundary-layer solution is presented to study the effects of viscous and Joule heating on unsteady natural convection flow in a micropolar fluid. Viscous dissipation has been retained as a first-order term. Numerical results for the unsteady boundary-layer equations have been obtained at any point along the vertical plate using the finite-difference method. Details of the velocity, microrotation, and temperature fields are presented for various material parameters.PACS Nos.: 44.25+F, 47.27-i, and 47.27Te
