HARTMANN FLOW AND HEAT TRANSFER OF COUPLE STRESS FLUID IN A POROUS MEDIUM BETWEEN TWO PARALLEL PLATES WITH PERIODIC SUCTION AND INJECTION
摘要
In the present article, we consider the two-dimensional unsteady incompressible flow and heat transfer of an electrically conducting couple stress fluid in a porous medium between two parallel plates with the periodic injection and suction at the lower and upper plates, respectively. Assume that the plates are maintained at different temperatures changing periodically with time. The governing partial differential equations are reduced to nonlinear ordinary differential equations using suitable similarity transformations, then solved numerically by a quasilinearization technique. The effects of various fluid and geometric parameters on velocity components and temperature distribution are studied and shown graphically. In addition, the coefficient of skin friction and heat transfer rate at the lower and upper plate are discussed in detail and presented in the form of tables. The present results have good agreement with the published work.
