1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

2. Optimization of hot strip drawing test methodology for hot forming of aluminium alloys
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : The development of lightweight design for automotive applications has lasted for many years and is still increasing. Vehicles with light structures use less fuel, emit less CO2, and are better for the environment. READ MORE

3. Oil Autonomy of a Turbojet
University essay from KTH/FlygdynamikAbstract : The oil circuit of a jet engine is required to lubricate and cool mechanical parts. The oil is pumped from the oil tank and flows through heat exchangers. Then it is injected on the bearings for lubrication and cooling, before being scavenged at the bottom of the sumps and finally flows back to the oil tank. READ MORE

4. Optimization of circulating oil system for paper machine
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : At the beginning of this project the goal was to create a concept for a brand new oil return system for the drying section of BillerudKorsnäs Karlsborgs paper machine. The goal was changed during the project in consultation with BillerudKorsnäs. The cause of that was a too uncertain system specification. READ MORE

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.
University essay from Mälardalens högskola/Framtidens energiAbstract : 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.
