• VARIATION OF FLOW RATE IN CASE OF MHD FLOW OVER A MOVING INFINITE VERTICAL POROUS PLATE IN THE PRESENCE OF THERMAL RADIATION AND UNIFORM HEAT FLUX

K. JHANSI RANI*, CH. V. RAMANA MURTHY

Abstract


The case of variation of flow rate with respect to various flow entities in situation of MHD flow over a moving infinite vertical porous plate in the presence of thermal radiation has been examined in detail in this paper.  It is observed that, as the pore size decreases the flow rate is found to be decreasing. In each of these illustrations, it is seen that the applied transverse magnetic field influences the flow rate significantly. Further, as the magnetic intensity increases the flow rate is found to be inversely proportional. Also, increase in the intensity of the magnetic field contributes to the decrease in flow rate. For a constant pore size of the bounding surface and the frequency of excitation, increase in the magnetic intensity amounts to the decrease in the flow rate. Also, a back flow is observed in certain cases and is illustrated graphically. Further, decrease in Grashoff number (Gr) contributes to the increase in the flow rate.
