On the oscillating plate-temperature flow of a polar fluid past a vertical porous plate in the presence of couple stresses and radiation

The paper studies the two-dimensional oscillatory flow of a polar electrically conducting viscous incompressible Bossinesq fluid past an infinite vertical plate whose temperature varied periodically about a mean constant non-zero value with time. The governing equations of this class of polar fluids are known to exhibit a boundary layer phenomenon. Employing a standard perturbative series method, expressions are obtained for the flow variables—velocity, temperature and plate surface skin friction, highlighting the effect of viscous dissipation heating. The numerical results obtained agree with and compliment results of earlier studies and are discussed quantitatively with the aid of graphs outlining the effects of radiation on the velocity field.
