An Analysis of Heat Transfer in a Turbulent Heat Generating Flow with High Prandtl Numbers

Document Type


Publication Date



Turbulent heat transfer in a circular tube associated with heat generating fluid of high Prandtl number and wall heat flux is investigated analytically. In the present study, a more comprehensive surface renewal type model, the surface rejuvenation model is employed, which accounts for the fact that turbulent eddies do not generally reach the wall itself. Results of the bulk-to-wall temperature difference on the basis of this model are presented graphically in terms of Reynolds number, Prandtl number and the ratio of wall heat flux to internal heat generation for both cases of heating and cooling. Some limiting solutions are compared with the available results in the literature.
