Transfer of heat and momentum in non-uniform turbulent flow

by Mason, John Latimer

Abstract (Summary)
Determinations of pressure, temperature and velocity as functions of position in a non-uniform, steady, two dimensional, turbulently flowing air stream have been made under four different flow conditions. Values of the eddy viscosity and eddy conductivity have been calculated and compared to those obtained under conditions of uniform flow. Bulk temperatures have been computed and compared with those obtained from existing empirical correlations. The general problem of predicting temperature and velocity fields in non-uniform flow is discussed. Previous theoretical work is compared with the experimental results of this work. The further research necessary to solve this problem for the case of fully developed turbulent flow is outlined. The partial differential equation for heat transfer has been solved for one of the above four flow conditions by means of an electrical analogy. Use has been made of eddy conductivity data obtained for uniform flow. This work is evaluated in light of the accompanying experimental results, and plans for further analog work are outlined.
