16. Fundamental Experimental and Numerical Investigation Focusing on the Initial Stage of a Top-Blown Converter Process
Sammanfattning : The aim of this thesis work is to increase the knowledge of phenomena taking place during the initial stage in a top blown converter. The work has been done in a few steps resulting in four different supplements. Water model experiments have been carried out using particle image velocimetry (PIV) technology. LÄS MER
17. Heat-transfer simulations applied to electrical machines
Sammanfattning : Electrification and energy efficiency are two important aspects in present scenarios describing a sustainable future. Electric motors constitute a large fractionof industry’s electricity demand today, and it is expected to remain high inthe future. LÄS MER
18. Resonant Laser Techniques for Combustion and Flow Diagnostics
Sammanfattning : This thesis presents results from two areas of research. Firstly, the resonant coherent laser techniques polarization spectroscopy (PS), degenerate four-wave mixing (DFWM) and stimulated emission (SE) have been developed in the general field of combustion diagnostics. LÄS MER
19. On the performance of stratified ventilation
Sammanfattning : People nowadays spend most of their time indoors, for example in their homes, cars, in trains, at work, etc. In Sweden, the energy demand in the built environment is a growing issue. LÄS MER
20. Parametric Model for Astrophysical Proton-Proton Interactions and Applications
Sammanfattning : Observations of gamma-rays have been made from celestial sources such as active galaxies, gamma-ray bursts and supernova remnants as well as the Galactic ridge. The study of gamma rays can provide information about production mechanisms and cosmic-ray acceleration. LÄS MER
