  2. 1. Large eddy simulation of transonic flow with shock wave/turbulent boundary layer interaction

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

    Abstract : 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. READ MORE

  4. 2. Supersonic flow separation with application to rocket engine nozzles

    Author : Jan Östlund; KTH; []
    Keywords : turbulent; boundary layer; shock wave; interaction; overexpanded; rocket nozzle; flow separation; control; side-load; experiments; models; review;

    Abstract : The increasing demand for higher performance in rocketlaunchers promotes the development of nozzles with higherperformance, which basically is achieved by increasing theexpansion ratio. However, this may lead to flow separation andensuing instationary, asymmetric forces, so-called side-loads,which may present life-limiting constraints on both the nozzleitself and other engine components.

  6. 4. Hot wire and PIV studies of transonic turbulent wall-bounded flows

    Author : Timmy Sigfrids; KTH; []
    Keywords : fluid mechanics; compressible flow; turbulence; boundary layer; hot-wire anemometry; PIV; shock wave boundary layer interaction; shape factor;

    Abstract : The compressible turbulent boundary layer developing over atwo-dimensional bump which leads to a supersonic pocket with aterminating shock wave has been studied. The measurements havebeen made with hot-wire anemometry and Particle ImageVelocimetry (PIV). READ MORE

  7. 5. Transonic flow: large eddy simulation, numerical methods and subgrid modeling

    Author : Christian Wollblad; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; SGS modeling; Transonic flow; semi-implicit numerical scheme; shock wave turbulent boundary layer interaction;

    Abstract : Shock wave turbulent boundary layer interactions (SWTBLI) commonly arise in turbomachinery and aerospace applications and on the exterior of high speed aircrafts. In all these cases, SWTBLI can significantly change the flow and hence the physical load imposed by it. READ MORE
