Abstract:

The extension of simple two-dimensional turbulent boundary layer TBL concepts to three-dimensional flows has met with limited success due to non-equilibrium effects. Transport equations for some turbulent stresses are proposed to account for the non-equilibrium effects. This study is aimed at developing algebraic relationships among the various Reynolds-averaged terms in these equations to reduce the number of modeled parameters, specifically the triple products. Eleven existing experimental data sets, with a variety of flow geometries, that included all six Reynolds stresses and triple products were acquired from the original authors and re-examined with respect to algebraic parameters.
