11. Verification of HARMONIE-AROME, ECMWF-IFS and WRF: Visibility and Cloud Base Height
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : Visibility and cloud base height are two important parameters within aviation meteorology and verification of operational numerical weather prediction (NWP) models with regard to these two parameters is therefore important. Visibility is often parameterized through an extinction coefficient, which is dependent on for example liquid or ice water content, however it also depends on the humidity, precipitation intensity and particle concentration.

12. Forest Simulation with Industrial CFD Codes
University essay from KTH/StrömningsfysikAbstract : Much of the planned installation of wind turbines in Sweden will be located in the northern region, characterized by a lower population density so that problems related to sound pollution and visual acceptance are of lower concern. This area is generally distinguished by complex topography and the presence of forest, that significantly affects the wind characteristics, complicating their modelling and simulation. READ MORE

13. RANS & WMLES Simulations of Compressor Corner Separation
University essay from KTH/MekanikAbstract : In axial compressor, corner separation phenomenon can occur between the blade surface and the hub. This leads to high total pressure losses, blockage and may worsen to surge. Various studies on NACA65-009 blade were previously performed experimentally and numerically to predict the corner separation. READ MORE

14. Numerical simulations of mixing for gas exhaust treatment
University essay from KTH/Strömningsmekanik och Teknisk AkustikAbstract : According to the World Health Organisation, nine out of ten people live in places with sub par air quality. Therefore, the study of the treatment of polluted air is from a global point of view of great importance, and a matter of life quality for both humans and as well as animals. READ MORE

15. A COMPARISON OF THE OBSERVED WAKE EFFECT WITH SEVERAL WAKE MODELS USING BOTH ANALYTIC AND CFD SIMULATION METHODS - FOR THE CASE OF BLOCK ISLAND OFFSHORE WIND FARM
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : This paper sets out to analyze the observed wake effect at Block Island Wind Farm. A comparison is made between several wake simulation methods and the observed data at Block Island using analytic and CFD (Computational Fluid Dynamics) modelling methods. READ MORE
