The modelling of the pressure strain rate terms is an important issue in the improvement of the generality of closure models for the Reynolds stress transport (RST) equations. A part of these efforts is to provide accurate experimental information on the pressure-strain rate tensor, which in turn requires equally accurate information on the dissipation and diffusion tensors. Here the far wake of a cylinder was studied in order to enable the required balances of the RST equations. The experimental results indicate a nonisotropic dissipation tensor, and show the energy redistribution between the different components as described by the pressure-strain rate correlations. Comparisons are made between the experimentally determined pressure-strain rate distributions and the corresponding distributions predicted by closure models.
