A Study of Heat Transfer by Turbulence

This paper consists of four main divisions. The first of these is a discussion of turbulence in a flowing fluid and of how heat and momentum are transferred thereby. The second is a presentation of the problems met in constructing the apparatus with which to measure the pertinent quantities connected with turbulent transfer. The third is a description of the method of calibration of the measuring instruments. The fourth is a presentation of the experimental results obtained; these results, however, are so limited in quantity that they serve merely as an indication of those to be expected in the future.
