41. Rotational Coherent Anti-Stokes Raman Spectroscopy: Experimental and Theoretical Developments in Gas-phase Thermometry
Sammanfattning : Dual-broadband pure rotational coherent anti-Stokes Raman spectroscopy was investigated in terms of thermometry and species concentration measurement for studies of combustion. The modelling of rotational CARS spectra under conditions of high pressure at room temperature was investigated. LÄS MER
42. Zero and Multi-Dimensional Modeling of Internal Combustion Engines with respect to Ion Current and Soot Formation
Sammanfattning : The work presented in this thesis can be divided into the three following fields of investigation: First of all the ionization model developed in this thesis is meant to simulate the thermal ionization process or the so-called second peak. Equilibrium assumptions have been adopted for the modeling of the thermal ionization, in which Saha’s equation was derived for singly ionized molecules. LÄS MER
43. Short-Pulse Laser Spectroscopy for Combustion Diagnostics - Laser-Induced Fluorescence of Polyatomic Molecules and Developments in Measurement and Evaluation
Sammanfattning : Combustion is the most important source of energy worldwide. A better understanding of it is essential if pollutant emissions are to be reduced and combustion devices be made more efficient. This requires measurement of physical and chemical combustion parameters. LÄS MER
44. Fundamental studies on the high temperature corrosion mechanisms of a 22Cr austenitic stainless steel in environments related to oxy-fuel combustion
Sammanfattning : This thesis concern the high temperature corrosion mechanisms of stainless steels, with focus on a 22 wt.% Cr FeNiCr alloy (Sanicro 25), in environments related to oxy-fuel combustion, which is a promising technology that can provide enhanced CO2 recovery and sequestration from power plants by using post-combustion capture.

45. Considering external costs : Their influence on technical measures in energy systems
Sammanfattning : It is well known that conversion of energy gives rise to several environmental problems. The impact on the environment and human health can involve substantial indirect costs for society. These indirect costs are also known as external costs, since the market often does not consider them. LÄS MER
