1. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. LÄS MER
2. Design Investigation into Liquid Oxygen Vaporisation Systems : Atomisation and Heat Loads
Master-uppsats, KTH/EnergiteknikSammanfattning : Computational Fluid Dynamics (CFD) simulations are presented within this study for super-cooled liquid oxygen atomisation and gasification in a subcritical chamber operating at 1MPa. Relatively low cost simulation techniques have been used and their accuracy evaluated. LÄS MER
3. Piston bowl combustion simulation - From fuel spray calibration to emissions minimization
Master-uppsats, KTH/MekanikSammanfattning : The current pollution policies in all European and American countries are forcing the industry to movetowards a more efficient and environmentally friendly engines. On the other hand, customers requiremaintaining the power and fuel consumption. LÄS MER
4. Analysis of human exposure at local exhaust ventilation by means of 3D air velocity measurements, tracer gas tests and controlled turbulence environment
Magister-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknikSammanfattning : Local exhaust (LE) ventilation is a ventilation technique where contaminated air is locally extracted close to the contaminant source usually with the purpose to reduce the exposure of workers to dust, fumes or vapour, which can be hazardous to their health. The performance of a LE installation depends however on many influential factors, and there is not yet an international standardized way to test LE constructions. LÄS MER
5. Investigation of Common Wear Factors in the Diesel Engines Fuel System, in Order to Develop Accelerated Life Evaluation Tests
Master-uppsats, Linköpings universitet/Fluida och mekatroniska systemSammanfattning : The task of this thesis is to analyse the wear factors in a diesel engine fuel system. Tests based on common documented wear factors and theory will be used in order to develop and localize the wear enhancing inputs during usage. LÄS MER
