Application of PDF modeling to swirling and nonswirling turbulent jets
The authors apply the probability density function methods to the modeling of turbulent swirling and nonswirling coaxial jets, and temporal shear layer. A pressure transport model is implemented in conjunction with several velocity models. The complete model demonstrates a good comparison with available experimental data in the low swirl case. The crucial factor in determining the quality of coaxial jet simulations is a proper specification of a parameter ratio in the modeled source of turbulent frequency. The parameter specification is also shown to be significant in the temporal shear layer.
