Abstract

We scrutinize new and previously published Large Eddy Simulation (LES) data for a sonic jet injected into a supersonic crossflow. Jet and crossflow consist of air, the crossflow Mach number is M_∞ = 1:6 and the jet to crossflow momentum ratio is J = 1:7. For this case, experimental measurements and rich numerical data are available in literature. Results of previous numerical studies and our LES are in excellent agreement. However, all numerical data sets show very similar deviations from the available measurements. We analyse sensitivities on uncertain flow parameters to identify the parameters that are most likely responsible for the discrepancy between the numerical and experimental data.
