Forced heat convection in turbulent flow over a flat plate of a finite width

The convective heat transfer over a finite-width plate immersed in a turbulent boundary layer has been experimentally characterized, with emphasis on the enhancement induced by the side-edge effect. It is found that the heat transfer over a finite width plate is strongly promoted by the side-edge effect and is primarily attributable to a secondary flow occurring near the side-edge. The region of influence of the side-edge effect depends on plate thickness more strongly than on the plate width and extends toward the plate center with increasing plate thickness. The heat transfer enhancement due to the side-edge effect depends mainly on the plate thickness. The heat transfer coefficient can be estimated in terms of the Stanton number using the plate thickness as a parameter. Empirical formulas to evaluate the local and mean heat transfer coefficients are given.
