SINOPSIS
Computations of a fully pulsed air jet are presented using a two-scale eddy-viscosity based scheme and an advanced stress transport model. Like other single scale models, the stress transport scheme fails to capture many features of the flow. In contrast, the two-scale model, however, does reproduce some important elements of the flow development. Further examination of the model performance suggests that its success is due in part to the implied spectral non-equilibrium, but also to the particular form of source terms employed in the transport equation for the turbulence energy transfer rate.
