HEAT TRANSFER IN A CHANNEL WITH RANDOM VARIATIONS IN FLUID VELOCITY

pages 1-10

Abstract

Heat transfer results have been obtained for randomly varying laminar flow in a heated parallel plate channel. Two types of heat transfer boundary conditions are considered: (a) The channel walls are at constant temperature; or (b) a specified uniform heat flux is transferred at the walls. The heat transfer behavior is obtained along the entire length of the channel. The temperature distributions are two-dimensional but a slug flow velocity profile is assumed. The results show significantly higher mean wall temperatures and, for short channels, lower wall heat fluxes when compared to the steady flow cases.
