HEAT TRANSFER IN A RADIATING FLUID WITH SLUG FLOW IN A PARALLEL-PLATE CHANNEL
Fully developed heat transfer in slug flow in a flat duct between two parallel plates was studied. The flat duct consists of two diffuse, nonblack, isothermal surfaces. The gray radiating fluid between theri is capable of emitting and absorbing thermal radiation. The problem was formulated in terms of a nonlinear integrodifferential equation, and the solution was obtained by an approximate method. The differences between heating and cooling the fluid were examined. The effects of the optical thickness of the fluid, the ratio that deterriines the relative role of energy transport by conduction to that by radiation, and the emissivity of the duct surfaces on the temperature distribution and the heat transfer characteristics were investigated. An approximate method for calculating the radiant heat flux at the wall is presented, and the accuracy of the approximation was tested. (P.C.H.)
