The role of turbulence in determining the heat-transfer characteristics of impinging jets

Abstract Data on the variation of local heat-transfer coefficients produced by impinging jets have been re-examined in the light of measurements of the velocity and turbulence distributions in submerged jets and in the context of other work on the influence of turbulence on heat transfer. It is shown that some seemingly anomalous heat-transfer phenomena can be explained as effects of the intense and spatially varying turbulence inherent in jets.
