1. Numerical Modeling of Atomization in Spray Systems
Sammanfattning : Dispersed multiphase flows refer to dynamic systems comprising two or more phases where at least one phase is in the form of fine particles evolving in and interacting with a surrounding fluid. Spray systems fall into that category. LÄS MER
2. Studies on Diesel sprays under non-reacting and reacting conditions
Sammanfattning : Methods for reducing engine-out emissions are urgently needed to mitigate climate change and air pollution. In diesel engines, the quality of fuel-air mixing and the subsequent combustion process strongly affect fuel efficiency and engine-out emissions. LÄS MER
3. Numerical Studies of Methanol PPC Engines and Diesel Sprays
Sammanfattning : The global environment suffers from utilizing fossil fuels to powering internal combustion engines (ICE), due to the massive amounts of released CO2. Besides the global impact, the local environments experience high concentrations of harmful pollutants such as NOx, CO, soot and particulate matter (PM). LÄS MER
4. New Materials and Improved Ambient Techniques in Mass Spectrometry
Sammanfattning : Mass spectrometry (MS) is used in several fields, e.g. biology, environmental monitoring, medicine and forensics due to excellent qualitative and quantitative capabilities. The development of new instrumental setups and ionization sources is crucial to analyze a variety of compounds at trace levels. LÄS MER
5. LES stochastic modelling of cavitation with its applications in OpenFOAM
Sammanfattning : Cavitation is a vaporization process that commonly happens in high-pressure injector nozzles nowadays. It has been shown by previous studies that cavitation has a significant influence on the subsequent atomization process, the quality of which would in turn heavily affect the process of combustion.
