WP-4 Internal Flows—Turbine

Effect of Jet Vortex Generators on Shock Wave Induced Separation on Gas Turbine Profile

“…In the paper, selected experimental data presented in Ref. [11] are shown as the reference for numerical simulations.…”

“…8 Shock wave structure visualized by density gradient [11] Fig. 9 Separation visualized by iso-surface of negative velocity [11] The λ-foot height is reduced as well as the separation length downstream of the shock wave due to the effect of film cooling and generated streamwise vortices on the upstream boundary layer. The separation reduction is shown in Fig.…”

“…As it is mentioned above, in the presented single passage test section there is no possibility to investigate various operating conditions or aerodynamic performance of cascade. The presented results were considered as the first step of investigations and cascade measurements in DLR Goettingen [11].…”
