To be able to study high pressure properties and synthesis of carbon nanostructures, we built a pressure control box to regulate and fine tune pressure to our membrane diamond anvil cell (MDAC). Using ruby fluorescence method, we calibrated the pressure in the membrane against the generated pressure in the cell. This resulted in both a [...]
CFD Simulations of Pressure Loss in Pipes with Different Geometries
The passive security systems protect the passengers when the car has an important accident. These systems are based in a good and strength car structure to not deform the passenger cabin. In Gestamp Hardtech are producing pieces with an important strength without increasing the car weight. These pieces are produced using the hot stamping process [...]
Study of the reactions between iron ore slag and refractories
For the fabrication of iron ore pellets at LKAB (Luossavaara-Kiirunavaara AB), one of the methods used is to sinter the pellets in a rotary kiln. This Kiln has a drift temperature of 1250°C in average. During this process a coating, causing the wear of the refractories materials, is formed, inducing expensive maintenance periods. The aim [...]
Improved aero blade design for multi-disciplinary integration
Robust design and reduced lead-time are key issues in the general field of product development today. The meaning of KEE (Knowledge Enabled Engineering) can be generalized as a process to customize computer aided engineering systems to reduce the lead time for routine engineering work as well as securing the design “know-how” for specific components. As [...]
Improved stability analysis of rocket engine nozzles
This master’s thesis was conducted at Volvo Aero Corporation (VAC) in Trollhättan at the department of combustion chambers and nozzles. This department is responsible for the development of the main engine nozzle extension to the European Ariane 5 rocket. During space flight there are a variety of loads which may cause structural instability in the [...]
