On flow past a continuously moving semi-infinite vertical plate in the upward direction

Flow past a continuously moving semi-infinite vertical plate in the upward direction is studied here. With usual boundary layer transformations, the boundary layer equations are reduced to local non-similar ordinary differential equations which are solved numerically. Velocity and temperature profiles are shown on graphs and the numerical values of the skin-friction and the rate of heat transfer are listed in a Table. It is observed that there occurs separation of low Prandtl number fluids at large values of Gr/Re2 where Gr is the Grashof number and Re is the Reynolds number. Greater viscous dissipative heat causes a fall in both the skin-friction and the rate of heat transfer.
