Abstract

Heat transfer in turbulent flow from external surfaces has been investigated extensively in the past. Most of the theoretical and experimental work deals with a two dimensional boundary layer on isothermal or uniform heat flux surfaces with longitudinal temperature variation. However, little attention has ever been paid to the case in which the temperature of the plate varies transversely. This is a three dimensional problem due to the spanwise variation of the thermal boundary layer. The most elementary example of this is the boundary formed by the sudden temperature impulse that acts transversely across a flat plate as shown in Fig. 1. Theoretically, this spanwise boundary increases the heat transfer coefficient. A knowledge of this is important in the field of heating and cooling system design. It is also important for the investigation of spot-heat flux measurement.
