1. Large eddy simulation of transonic flow with shock wave/turbulent boundary layer interaction
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
2. Supersonic flow separation with application to rocket engine nozzles
Sammanfattning : 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.

3. Flow Processes in Rocket Engine Nozzles with Focus on Flow Separation and Side-Loads
Sammanfattning : .... LÄS MER
4. Hot wire and PIV studies of transonic turbulent wall-bounded flows
Sammanfattning : 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). LÄS MER
5. Transonic flow: large eddy simulation, numerical methods and subgrid modeling
Sammanfattning : 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. LÄS MER
