   Abstract : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. READ MORE

3. 2. Establishment of an open 3D steam turbine flutter test case

   University essay from KTH/Energiteknik

   Author : Di Qi; [2016]
   Keywords : ;

   Abstract : An open three-dimensional (3D) flutter test case for steam turbines is presented. Unlike previous research on turbine flutter, the geometry is an open resource and is from a test case originally presented by Durham University. READ MORE

4. 3. CFD computations of hydropower plant intake flow using unsteady RANS

   University essay from KTH/Kraft- och värmeteknologi

   Author : Lovisa Nöid; [2015]
   Keywords : CFD; Vortex; URANS; Hydropower;

   Abstract : At the intake of hydropower plants, air-core vortex formation is known to cause severe damage. In order to study how to prevent and reduce the origin of the vortex, Vattenfall has built a scale model of the Akkats hydropower plant dam, where scale testing is possible. READ MORE
