Free convection effects on the oscillatory flow of an incompressible viscous fluid past an infinite, vertical plate with variable suction
Abstract
An analysis of a twodimensional flow of an incompressible viscous fluid past an infinite vertical porous plate has been carried out under the following conditions: (1) the suction velocity normal to the plate varies periodically with time; (2) the freestream velocity oscillates in time about a constant mean; and (3) there is a temperature difference between the constant plate temperature and the freestream temperature, causing free convection currents in the boundary layer. Approximate solutions for the transient velocity, the transient temperature, the amplitude and phase of the skin friction, and the rate of heat transfer are derived. The fluctuating parts of the velocity profiles, the transient velocity, and the transient temperature are plotted, while numerical values of the amplitude and phase of the skin friction and the rate of heat transfer are tabulated. The results are discussed in a quantitative way.
