Abstract: CFD simulations of a slanted jet in crossflow were made and compared to detailed 3D-LDA measurements. Three turbulence models were studied using Fluent v6.1: realisable k-ε, SST-k-ω and Reynolds stress model (RSM). The SST-k-ω model and the RSM were both able to capture the recirculation zone in the jet wake, which was not the case with the realisable k-ε model. The turbulent kinetic energy field was not well predicted by the k-ε or the SST-k-ω model. However, the Reynolds stress field was captured qualitatively correct by the RSM.
