Abstract
Interest in the course of chemical reactions in turbulent flow has made desirable detailed knowledge of the temperature distribution in flowing streams. One method of predicting the temperature distribution under a variety of conditions is reviewed here, the approach being limited to conditions of local uniform transport of momentum. A discussion of some of the aspects of eddy conductivity is included along with a brief review of the velocity distribution in uniform flow.The results serve to illustrate the relation of microscopic conditions of flow to the temperature distribution in a turbulently flowing stream. The importance of the molecular Prandtl number upon the transfer process is stressed.
