NUMERICAL INVESTIGATION OF FREE CONVECTION AND HEAT TRANSFER BETWEEN VERTICAL PARALLEL PLATES WITH DIFFERENT TEMPERATURES
要約
Results are presented of a numerical investigation of the flow and heat transfer in laminar free convection between vertical parallel isothermal plates with different temperatures above and below the ambient. The Prandtl number was constant Pr = 0.71, and the Rayleigh number changed within (Ra = 103 − 105). The ratio of geometrical sizes of plates and distances between them was constant A = L/w = 10. The Navier-Stokes and energy equations could be solved completely by the method of finite volumes on staggered meshes. The effect of temperature ratio on the flow structure at the channel inlet and outlet was analyzed. Data on velocity and temperature distributions between the plates and local and integral heat transfer are presented; this allows better understanding for the mechanism of transfer processes between the parallel plates with asymmetric heating.
