1. 1. CFD investigation of a unit cell inside a Plate Heat Exchanger

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Mattias Ly; [2023]
   Keywords : Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

   Abstract : 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

3. 2. Development of a Shrouded SteamTurbine Flutter Test Case

   University essay from KTH/Kraft- och värmeteknologi

   Author : Ren Jinghe; [2017]
   Keywords : shrouded blade; flutter; hot-to-cold; CFD; höljet; fladdret; hot-to-cold; CFD;

   Abstract : A shrouded blade was designed as a test case for flutter analysis of steam turbine. Flutter is a self-excitedvibration. It can lead to dramatic blade loss and high-cycle fatigue. Shrouded blade is more complicated onflutter analysis, because the mode shapes are more complex with bending and torsion components atdifferent phases. READ MORE

4. 3. Quantification and Absorbed Dose Estimation of I-124 using microPET

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Magnus Hörling; [2007]
   Keywords : Nukleärmedicin; Medicine and Health Sciences;

   Abstract : Small-animal positron emission tomography (PET) has proven to be a promising and useful modality for preclinical pharmacokinetic studies. Thanks to high sensitivity and spatial resolution in the range of a few millimetres, the possibility to perform reliable and accurate quantification and absorbed dose estimates is within reach.
