Résumé :
|
A model of turbulence is investigated in which the Reynolds stress appearing in the momentum equation is calculated. These equations are solved for various free-jet situations, and the empirical constants involved are adjusted so as to give best agreement between predictions and experimental results. The plane mixing layer, the plane jet and the radial jet can be predicted with a single set of constants ; for the round jet a different set has to be used. Comparisons are presented of predicted and measured rates of spread and energy balances. For most cases the agreement is within the experimental accuracy.
