Average Heat-Transfer Characteristics of a Row of Circular Air Jets Impinging on a Concave Surface

摘要

A study of the average heat-transfer characteristics of air jets impinging on the concave side of a right-circular semicylinder is reported. Results from existing correlating are compared with each other and with experimental heat-transfer data for a row of circular jets. Two correlations available in the literature are recommended for use in designing cooled turbine vanes and blades. (Author)
