| Popis: | International audience; This study presents simulations and experiments on the effect of porous bleed systems on a supersonic turbulent boundary layer at a Mach number of M=1.6. The results indicate a good fit between the RANS simulations and the experiments based on LDV, BOS, and pressure measurements. The numerical simulations well capture the overall flow topology. Both approaches show the same trend of fuller profiles with higher suction rates. The findings suggest that RANS simulations can be used to investigate the effect of bleed systems for different bleed parameters to improve bleed models. Overall, this study provides valuable insights into the working principle of bleed systems, which are crucial for designing and optimizing supersonic air intakes. |
