Variable-Density Co-Flowing Jet Simulations with BHR

Recent experiments by the Extreme Fluids team at Los Alamos National Laboratory have examined a jet of SF6 injected into co-flowing air. The experiment is designed to aquire detailed diagnostics for comparision to turbulence models. Simultaneous PIV/PLIF is used to measure the Reynolds stress and velicty-density correlations. In the current work, the BHR RANS model is being implemented in an incompressible variable-density code, and compared to the experimental results. Since the jet is not self-similar, both due to co-flow and variable density effects, careful attenstion is payed to the role of inflow conditions. Also, some multi-jet configurations are explored.
