Analogy between heat transfer and mass transfer in a plane turbulent wall jet
Abstract
The relationship between heat transfer and friction coefficient at the wall in a plane turbulent wall jet is investigated experimentally and theoretically. Pressure sensors, hot-wire anemometers, and Preston tubes are used to characterize the flow in an orifice of thickness 7.13-20.5 mm above a 50-cm-wide 150-cm-long heated plate at Reynolds numbers 9000-60,000. The results are presented in graphs; a theoretical model is developed to describe the evolution of the skin-friction coefficient; and an expression relating heat transfer and skin friction and explaining published experimental heat-transfer data is obtained.
