Fundamental Research in Turbulent Modeling.

Abstract

A summary of both the theoretical and experimental studies carried out during the first year of a program of fundamental research on turbulent modeling is given. On the theoretical side, the application of a modeled tensor scale equation together with a modeled Reynolds stress equation to the case of homogeneous shear flow is discussed in some detail. It is shown that such modeling gives results that are in good agreement with experiment. On the experimental side, preliminary data on the effect of swirl on the structure of turbulence in an annular pipe flow are presented. (Author)
