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. Fluid flow features in swirl injectors for ethanol fueled rocket : - Analysis using computational fluid dynamics
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : A swirl injector for a rocket engine being developed by \emph{AESIR} (Association of EngineeringStudents in Rocketry) was simulated with different geometric parameters. The swirl injector is usedto atomize the ethanol used as fuel and to create a spray that mixes well with the oxidizer withinthe combustion chamber. READ MORE

3. Development of Test Rig and Experimental Evaluation of Hydrostatic Bearings for an Axial Flux Machine
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : A novel electric machine design, similar to an axial flux machine, incorporates hydrostatic bearings to increase efficiency and stability of said machine. In this thesis, the feasibility of a hydrostatic solution is explored and evaluated by development, manufacturing, and assembly of a test rig, as well as running experimental tests with it. READ MORE

4. Dynamic Torque Modeling of a Wet Lamella Clutch Pack
University essay from Lunds universitet/Industriell elektroteknik och automationAbstract : Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. READ MORE

5. Acoustic Analysis of Wave-Guide and MEMS Microphone in Camera Including Thermoviscous Losses
University essay from Blekinge Tekniska HögskolaAbstract : Today Micro Electrical Mechanical Systems (MEMS) microphones are available in a range of electronic consumer products such as smart phones, tablets, smartwatches and surveillance cameras. The MEMS microphones are usually attached to a circuit board with a hole that lets sound propagate through, as well as additional wave-guides which alter the MEMS microphones original frequency response.
