(INDIA) Department of Mathematics, Sri Venkateswar Institute of Science & Technology, Kadapa - 516 003 (A.P.) INDIA <p style="text-align: justify;">In this paper, we studied the MHD oscillatory flow of a micropolar fluid through a porous medium over a vertical porous plate. The expressions for the velocity field, angular velocity and temperature filed are obtained analytically. The effects of time <em>t</em>, Hartmann number <em>M</em>, Darcy number <em>Da</em>, Grashof number <em>Gr</em>, viscosity ratio b and micro-gyration vector on the velocity field, angular velocity and temperature filed studied in detail.</p> <p style="text-align: justify;">&nbsp;</p> https://www.ultrascientist.org/paper/1269/ MHD micropolar fluid porous medium Grashof number
