Free Convection Heat Transfer in a Stably Stratified Fluid between Vertical Plates. The Effects of the Initial Temperature of the Fluid on the Heat Transfer under the Condition of Constant Wall-Temperature.

Inner cylinder diameter effects on free convection heat transfer in a stable stratified fluid

“…Thus the temperature profile becomes rather uniform, though small fluctuation exists on the profile. As seen in the case of a stably stratified fluid between vertical plates [6,[16][17][18], according to the relation between the thickness of the convection layer and the heat transfer coefficient, the heat transfer coefficient, when a convection layer has an appropriate thickness, can be larger than that for a non-stratified fluid. In the case of Fig.…”

“…Consequently, recently the authors have been systematically investigating free convection heat transfer in a stably stratified fluid. As a part of the systematic works, the effects of a temperature difference between heat transfer plates, initial density gradient and the initial temperature of the fluid have been investigated on the flow and heat transfer in the stratified fluid, when a stably stratified fluid is heated and cooled laterally between vertical plates [16,17]. Furthermore, the effects of the heating condition, i.e., heating at a constant temperature or a constant heat flux, were investigated by conducting experiments for heating at a constant heat flux between vertical plates and comparing the results with previous works [18].…”
