Parameter Influence on Porous Bleed Performance for Supersonic Turbulent Flows

Autor: Giehler, Julian, Grenson, Pierre, Bur, Reynald

Porous bleed systems are a common technique to control shock-boundary layer interactions and/or supersonic boundary layers. However, the influence of various design parameters is still unknown. Even though bleed models are required to minimize the co
