1. CFD-simulering av värmeöverföring under upptändningsförlopp av krutraketmotor
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : SAAB Dynamics producerar och utvecklar flertalet produkter som innehåller krutraketmotorer. Krutraketmotorers prestanda är kraftigt beroende av en effektiv upptändning och det är önskvärt att kunna prediktera detta förlopp numeriskt med god noggrannhet. Ingen etablerad simuleringsmetodik existerar i dagsläget. LÄS MER
2. Wall-Resolved and Wall-Modelled LES for a NACA4412 Wing Profile in OpenFOAM
Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : The purpose of this study is to perform computational fluid dynamics (CFD) simulationfor an incompressible flow around an airfoil and investigate the aerodynamicproperties for different Reynolds numbers (400, 000 and 1, 000, 000) based on the chordlength, at the moderate angle of attack (AoA) of 5o . For this purpose a detailedevaluation of wall-resolved and wall-modelled large-eddy simulations (LES) wereconducted for the NACA4412 wing profile. LÄS MER
3. Aerodynamics simulations of Scania trucks using OpenFOAM
Master-uppsats, KTH/Teknisk mekanikSammanfattning : 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. LÄS MER
4. Conjugate Heat Transfer Analysis of HPGP Thruster
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : 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. LÄS MER
5. Modelling Micropollutant Removal Through Ozonation in Wastewater
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Proper management of water resources is a key to climate change adaptation and resilience in modern societies. Adequate treatment of wastewater is essential for ensuring the sustainability of the water cycle and the health of the environment and the ecosystems that inhabit it. LÄS MER
