1. Numerical evaluation of the ground vortex
Master-uppsats, KTH/Teknisk mekanikSammanfattning : This master thesis covers the realization of a CFD calibration study regarding the numerical simulation of the ground vortex phenomenon. As part of InVIGO project (EU CleanSky2), wind tunnel test campaigns were performed using a nacelle model combined with a movable raised floor. LÄS MER
2. Parametric Study of Separation in Outlet Diffuser of Rocket Nozzle Cooling Channel Rig : The Effect of Heat Flux and Angle of Outlet Diffuser for Rectangular-to-Circular Cross Section Transitions
Master-uppsats, KTH/Farkostteknik och Solidmekanik; KTH/Kraft- och värmeteknologiSammanfattning : The use of natural gas with high methane content as rocket fuel has gained substantial industrial attention over the past number of years. Several actors including SpaceX and Blue Origin are developing natural gas powered rocket engines. LÄS MER
3. Pix
Kandidat-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologiSammanfattning : This thesis is about the creation of a new game framework named Pix and a comparison between it and the game engine Godot. The purpose is to create a game framework that focuses on making the workflow streamlined for the pro- grammer and at the same time giving the programmer a lot of creative power. LÄS MER
4. Optimeringsmodell för globalt produktionsutbyte : Minimering av produktionskostnad för Scanias motorbearbetning
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistikSammanfattning : The engine production, machining and foundry at Scania is facing a higher production load and is, very soon, utilizing the whole capacity. Today, two production plants collaborate to meet global demand. However, the global structure of the planning process is missing. LÄS MER
5. Conceptual design and development of thermal management system for hybrid electric aircraft engine. : A study to develop a physical model and investigate the use of Mobil Jet Oil II as coolant for aircraft electrical propulsion under different scenarios and time horizons.
Master-uppsats, Mälardalens högskola/Framtidens energiSammanfattning : The ever-increasing levels of greenhouse gas emissions has led to the scientific community starting to explore the viability of electrical aircraft system, with the most prominent research and product development for hybrid electric system, which forms the transition phase from combustion to fully electric aircrafts. The primary objective of this thesis is to find solutions towards thermal management of the electrical components of a hybrid electric aircraft propulsion system, which generate a significant amount of heat while operating at heavy load conditions required to propel an aircraft.
