摘要：
The present report is a study of a transient magnetohydrodynamic (MHD) free convective flow of a viscous incompressible electrically conducting Casson fluid past a vertical oscillating plate in a rotating frame of reference embedded in a porous medium. The Casson fluid model is used to describe the non-Newtonian fluid behavior. The nondimensional governing equations are solved by using the Laplace transform technique for both cosine and sine oscillations of the plate. Effects of the embedded parameters on the velocity field, temperature distribution, shear stress, and rate of heat transfers at the plate are presented graphically. It is noted that the fluid velocity for cosine oscillations of the plate is much higher than that for sine oscillations of the plate.
