Influence of Radiation and Viscous Dissipation on Three-Dimensional Fluctuating Couette Flow and Heat Transfer with Suction/Injection
Краткое описание
An analysis of three-dimensional unsteady Couette flow between two horizontal parallel porous plates with radiation effect on temperature distribution is presented here. The lower stationary plate is subjected to transverse sinusoidal suction velocity distribution fluctuating with time and the upper porous plate in uniform motion is subjected to constant injection. Due to the periodic variation of suction velocity, the flow becomes three-dimensional. The heat transfer characteristic has also been discussed on taking viscous dissipation into account. The governing equations are solved by adopting complex variable notations and the expressions for the main flow, cross flow and temperature fields are obtained. The wall shear stress and rate of heat transfer in terms of amplitude and phase are finally discussed, incorporating the effects of main controlling parameters as they appear in the governing equations. The results of this parametric study are shown graphically and physical aspects of the problem are discussed.
