1. CFD investigation of a unit cell inside a Plate Heat Exchanger
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. READ MORE

2. A coupling method using CFD, radiative models and a surface model to simulate the micro-climate
University essay from KTH/Teknisk mekanikAbstract : The increasing demand for energy, depletion of fossil fuels, rising global warming, and greenhouse gas emissions have stimulated the need for widespread development and adoption of renewable energy sources (RES) worldwide. Among these sources, solar energy has emerged as a major contender to meet the growing demand. READ MORE

3. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE

4. 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

5. Stable Numerical Methods for PDE Models of Asian Options
University essay from Tillämpad matematik och fysik (MPE-lab)Abstract : Asian options are exotic financial derivative products which price must be calculated by numerical evaluation. In this thesis, we study certain ways of solving partial differential equations, which are associated with these derivatives. READ MORE
