| Abstract: | An approximate solution to oscillatory flow past a porous horizontal plate was carried out under the following conditions - (i) Constant suction
- (ii) Stratification of the medium due to change in density, viscosity and thermal conductivity
- (iii) Free-stream oscillation about a nonzero constant mean.
Solutions have been derived for the transient velocity, the transient temperature, the amplitude and the phase of skin friction and the amplitude and phase of the first and second harmonics of the rate of heat transfer. These are shown on the graphs. The effects of the suction parameter S, the stratification parameter λ, the frequency λ and the Eckert number E are discussed. |
