1. 6. 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

3. 7. Investigation of Scale Adaptive Simulation (SAS) Turbulence Modelling for CFD-Applications

   University essay from Mekanisk värmeteori och strömningslära; Tekniska högskolan

   Author : Victoria Wahlbom Hellström; Frida Alenius; [2013]
   Keywords : CFD; SAS; Scale Adaptive Simulation; CFD; SAS; Scale Adaptive Simulation; CFD; SAS; Scale Adaptive Simulation; CFD; SAS; Scale Adaptive Simulation;

   Abstract : Fluid dynamics simulations generally require large computational recourses in form of computer power and time. There are different methods for simulating fluid flows that are more or less demanding, but also more or less accurate. Two well known computational methods are the Reynolds Averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES). READ MORE

4. 8. U-RANS Simulation of fluid forces exerted upon an oscillating tube array

   University essay from KTH/Farkost och flyg; KTH/Aeroakustik

   Author : Lise Divaret; [2011]
   Keywords : Fluid-structure interaction; CFD; Forces; added mass; drag coefficient; Morison expansion; Unsteady Reynolds Averaged Navier Stokes simulations; Arbitrary Lagrange Euler model.;

   Abstract : The aim of this master thesis is to characterize the fluid forces applied to a fuel assembly inthe core of a nuclear power plant in case of seism. The forces are studied with a simplifiedtwo-dimensional model constituted of an array of 3 by 3 infinite cylinders oscillating in aclosed box. READ MORE
