5. 19. Large eddy simulation of transonic flow with shock wave/turbulent boundary layer interaction

   Författare :Christian Wollblad; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shock wave; turbulent boundary layer; LES;

   Sammanfattning : Large eddy simulations (LES) of shock wave/turbulent boundary layer interaction (SWTBLI) have been carried out. The flow configuration was that of transonic flow over a bump with inlet Mach number 0.75 and maximum Mach number 1.27. LÄS MER
