11. CFD Simulations of Flow Characteristics of a Piano Key Weir Spillway
University essay from Uppsala universitet/ElektricitetsläraAbstract : Comprehensive rehabilitation projects of dam spillways are made in Sweden, due to stricter dam safety guidelines for their discharge capacity. The Piano Key Weir (PKW) is an innovative design which has proven effective through several renovation projects made in many countries including France. READ MORE

12. Numerical study with computational fluid dynamics of hybrid rocket engine.
University essay from Luleå tekniska universitet/RymdteknikAbstract : In this thesis a Large Eddy Simulation (LES) of a hybrid rocket engine burning ethylene (C2H4) in nitrous oxide (N2O) is explored. This is done primarily using a solver and solution scheme provided by the Swedish Defence Research Agency (FOI) and an (at this date) unpublished chemistry model. READ MORE

13. Using CFD to investigate casue of vibrations in feed-water system
University essay from KTH/Strömningsmekanik och Teknisk AkustikAbstract : Computational fluid dynamics from large scale thermo-hydraulic simulation in 1D to large eddy simulation in 3D, were applied in this master thesis to study cause of vibrations in a feed-water system downstream the connected pumps. In the first step, the fluid flow of the pumps in RELAP5 simulations was disturbed by the blade passing sinusoidal vibrations to study their propagation in the piping system over time. READ MORE

14. Wind Forecasts Using Large Eddy Simulations for Stratospheric Balloon Applications
University essay from Luleå tekniska universitet/RymdteknikAbstract : The launch of large stratospheric balloons is highly dependant on the meteorological conditions at ground level, including wind speed. The balloon launch base Esrange Space Center in northern Sweden currently uses forecasts delivered through the Swedish Meteorological and Hydrological Institute to predict opportunities for balloon launches.

15. Interscale transport of Reynolds stresses in wall-bounded flows
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : Couette, pipe, channel, and zero-pressure gradient (ZPG) turbulent boundary layer (TBL) flows have classically been considered as canonical wall-bounded turbulent flows since their near-wall behavior is generally considered to be universal, i.e. invariant of the flow case and the Reynolds number.
