Abstract
Detached-Eddy and Reynolds averaged Navier-Stokes simulations of transverse (90 ) gaseous injection through a 15 half-angle diamond shaped orifice into a high Reynolds number (53 x 10 6 ) Mach 5.0 freestream was performed. The GASP and Cobalt CFD codes were employed in performing these simulations. RANS solutions along with instantaneous and time-averaged DES data were obtained for all cases. Numerical results were compared to available experimental data including surface oil flow visualization, shadowgraph photographs, pressure sensitive paint and pitot pressure. The goal was to evaluate the performance of turbulence models in predicting complex flowfields generated by transverse jet injection into high-speed flows. Results obtained indicate that both RANS and DES perform adequately in predicting the present flows. However, experimental results show higher entrainment and diusion downstream of the injector.
