Development/applications of tunable synchrotron VUV photoionization mass Spectrometry and laser spectroscopy techniques in combustion and energy conversion studies including experimental, theoretical and kinetic modeling study on combustion (pyrolysis, oxidation and flame), pyrolysis kinetics of biomass and coal, combustion related air pollutants.

My main research focus is to develop a deeper understanding of the reaction kinetics and laminar flames for energy transformation in power machinery. This concerns particularly high pressure and realistic current and future fuels, regarding also the formation mechanisms of combustion emissions. In my group, research work addresses challenges for chemical diagnostics under such conditions, specifically, developments of laminar flame propagation measurement methods and kinetic models for the combustion of liquid fuels at high pressures. This pertains especially to high-boiling-point fuels including transportation fuel components and alternatives. Efforts are also made to unravel intermediates and key pathways in low-temperature chemistry of hydrocarbon and oxygenated fuels, and explore fuel and oxidizer effects on combustion reactivity and PAH formation for hydrocarbon and sustainable fuels. Furthermore, my research interests also cover flame synthesis kinetics and spray/droplet combustion.

Vortex is the "sinew and muscle" of fluid motion, and the source of many unsteady and unstable flow phenomena. Presently, a major challenge encountered in developing all kinds of high-performance engines is the combustion instability, which is a complex mechanism involving the interactions among spray and atomization, chemical reaction, heat flow and even sound waves. To this end, my primary research interest is applying vortex dynamical analysis as well as experimental and numerical measures to understand the flow and flame instabilities associated with spray combustion. Flow and flame control techniques will be further developed to suppress the source of instabilities, thereby improving combustion stability and performance. These will be achieved through the following research thrusts: 1. Spray combustion 2. Combustion instability 3. Synthetic jet and flow control 4. Vortex dynamics 5. Unsteady aerodynamics

The main research is reaction kinetics, including combustion, catalytic reaction kinetics and the formation of combustion pollutants.

Hello and welcome to my research space! The advancement of cleaner combustion techniques is pivotal in boosting the efficiency and environmental sustainability of aircraft engines and gas turbines. My research encompasses several key areas: utilizing advanced laser diagnostic methods, reducing NOx emissions in low-carbon combustion, and mitigating thermoacoustic instabilities to improve these combustion processes. I am committed to pioneering innovative solutions that address critical challenges in carbon-free combustion technology, aiming for a future where energy and propulsion systems are both powerful and environmentally responsible.

My main research focuses on the fundamental combustion of carbon-neutral fuels. Concerning the emerging demands for stable and clean combustion technologies, investigations are performed on the combustion reaction kinetics and reaction regulation of carbon-neutral fuels such as hydrogen, ammonia, renewable synthetic fuels and biofuels. Specifically, experimental and kinetic efforts are made on the deeper understanding of combustion characteristics over a wide range of engine-relevant conditions, the construction of predictable combustion kinetic models with wide-applicability, the exploration on contributing factors and controlling mechanisms of combustion reactivity and pollutant formation, and the development of combustion reaction regulation strategies for carbon-neutral fuels.
