1. 1. Aerodynamics simulations of Scania trucks using OpenFOAM

   University essay from KTH/Teknisk mekanik

   Author : Ziyi Liu; [2024]
   Keywords : Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

   Abstract : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. READ MORE

3. 2. Conjugate Heat Transfer Analysis of HPGP Thruster

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Lisa Svensson; [2024]
   Keywords : aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

   Abstract : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done. ECAPS is a Swedish propulsion company specializing in green propulsion. They develop thrusters for spacecraft orbit and attitude control, utilizing the propellant LMP-103S. READ MORE

4. 3. Groundwater Modelling in southeast Cambodia - Facing irrigation and groundwater level changes during a pandemic

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Svea Bertolatus; [2024]

6. 5. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications

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

   Author : Eglantin Gjoni; [2023]
   Keywords : ;

   Abstract : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. READ MORE
