1. 21. Design Optimization of Savonius Wind Turbine using CFD Simulations

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Vatsalkumar Manavar; [2023]
   Keywords : Savonius wind turbine; Computational fluid dynamics; Vertical axis wind turbine; Overlap ratio; Distance between blades; Power coefficient;

   Abstract : This thesis is based on a simulation of the Savonius wind turbine. The Savoniusturbine is a simple vertical axis device, which has half cylindrical blades attached to the main shaft opposite to each other which creates the drag force from incoming wind and generates mechanical torque which drives the generator for electricity generation.

3. 22. Improving Water Droplet Prediction for Vehicle Exterior Water Management: Insights from Experimental and Simulation Studies

   University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Author : Anton Labbé; Mahim Ahsan; [2023]
   Keywords : Computational Fluid Dynamics; Volume of Fluid; Kistler Correlation; Water Droplet; Wind Tunnel Measurement; Exterior Water Management.; Beräkningsfluidmekanik; Volume of Fluid; Kistler-korrelation; Vattendroppar; Vind Tunnel Experiment; Exteriört Vattenhantering.;

   Abstract : This thesis focuses on the study of water transportation on vehicle surfaces, which is crucial for ensuring the unobstructed operation of sensors and cameras in autonomous vehicles. The research aims to develop and validate experimental and simulation methods to enhance the understanding of water droplet behaviour and to create accurate models for computational fluid dynamics (CFD) simulations.

4. 23. 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

5. 24. Design of Experiment Based on Full Factorial CFD Spray Modelling

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Olle Faritzon; [2023]
   Keywords : CFD; spray; liquid; injection; DoE; Design of Experiment; fuel spray; Propane; LPG; OpenFOAM; Experiment; Fluid dynamics; maritime shipping; engine; Technology and Engineering;

   Abstract : Design of experiment is a powerful tool that can reduce the amount of physical testing needed to save resources, time and money. A CFD-setup was constructed in OpenFOAM-8, simulating injection of liquid propane with a standard multi-hole injector. The model was then validated against experimental results. READ MORE

6. 25. MODELLING OF HEAT TRANSFER OF RAILWAY SWITCH HEATING

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Siddharth Suresh Sumathi; [2023]
   Keywords : Conjugate Heat transfer analysis; transient analysis; CFD; insulation; measurement data uncertainties.; Konjugat Värmeöverföringsanalys; transientanalys; CFD; isolering; mätdata osäkerheter.;

   Abstract : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches. READ MORE
