The results of an experimental study of the heat transfer below normally impinging jets are presented. These results are correlated on the basis of the local mean flow and turbulent characteristics of the free jet that would exist in the plane of impingement were this plane to be removed. In order to make these local correlations possible, a rather extensive survey of the turbulent characteristics of the free jet used in the experiments is made that can be used in connection with previous studies of the local mean character of the jet. On the basis of the method of local correlations which is developed, a rationale for computing heat transfer distributions below impinging jets is suggested.
