Rayleigh measurements of species concentration in a complex turbulent flow

Fig. 3 Jet centerline velocity decay. x/do Conclusion It is shown that the PER scheme, based on a parabolic computation of the upstream boundary condition for an elliptic flow, leads to notable improvements in the prediction of confined jets. The additional computational effort is minimal and no arbitrary adjustments are required. A simple mixing length model may be adequate for this purpose. The results presented here encourage the application of this scheme to other flows presenting similar difficulties.
