Thesis abstract
My research activity focuses on the experimental study of an original low NOx hydrogen double-swirl burner. Since H2 burns without CO2 emissions, it is considered a viable substitute for traditional fossil fuels in turbines and turbojets. However, H2 presents challenges such as flashback and high NOx levels. Using swirl motion and optimized geometry, the mixing efficiency can be enhanced, thereby optimizing the combustion process. I plan to measure pollutant concentrations and use optical diagnostics techniques, including Stereo-PIV, tomographic BOS and UV imaging, to fully characterize burner behavior under various operating conditions.
Personal interest in my research theme
I’ve always been interested in combustion and actively follow the transition of the energy sector. Despite the ongoing shift away from fossil fuel usage, I firmly believe that combustion will continue to play a crucial role as an energy source in the coming decades. Hydrogen, known for its CO2-free combustion, stands out as a promising alternative to traditional fuels. However, its successful integration poses significant challenges that necessitate further research and development to support renewable energy efforts and effectively reach net-zero emissions targets.
