Research Field
Aiming at the sustainable development requirement of energy, power, and environment, we focuse on the low-carbon, high-efficiency, clean, and safe combustion technologies for aero-space engines and gas turbines, in order to enhance engine performance, reduce pollutant emissions, and facilitate the orderly transformation of fossil, renewable, and aero-space fuels. The research areas include combustion diagnostics, combustion under variable gravity conditions, and catalytic combustion.
Team Building
There are currently 11 staff members, including 1 researcher in a full professor-level position, 1 researcher in an associate professor-level position, and 3 postdoctoral researchers. There are also 26 graduate students, 8 of whom are international students.
Project Overview
In 2024, a total of 27 projects were undertaken, and 12 new projects were successfully secured. These included 1 international (regional) cooperation research project from the National Natural Science Foundation of China (NSFC), 1 general project from the NSFC, 3 youth projects from the NSFC,
etc.
In the area of combustion diagnostics, a multi-spectroscopy fusion highresolution Operando detection system for combustion was developed, with a measurement accuracy of 1 ppm, used for the analysis of key products and combustion characteristics in the combustion process of engine combustion chambers. A 50 kW hydrogen/ammonia swirl combustor was developed, achieving high-precision diagnostics of hydrogen/ammonia combustion characteristics and key intermediate components under a wide range of operating conditions. An in-situ wide-temperature-range combustion reaction diagnostic instrument based on Raman spectroscopy was developed, enabling
in-situ diagnostics of flames, combustion soot, pyrolysis coking, and catalytic reactions.
In the area of variable gravity combustion, a single/multi-jet combustor and soot sampling device for the combustion science experiment cabinet of the space station was developed. The device has been transported to the space station and is awaiting the conduct of combustion science experiments. Microgravity experiments were carried out, completing ethylene/methane microgravity combustion characteristic experiments and discovering the “soot meteor” phenomenon, providing data support for in-depth exploration of soot formation mechanisms.
In the area of combustion kinetics and reaction mechanisms, the combustion characteristics of low-carbon fuels such as C1-C4 hydrocarbons, C7-C11 alkylbenzenes, aviation fuel RP-3, C5-C7 nitrogen-containing aromatic heterocycles, and C3 amine compounds were revealed. The influence of highpressure conditions and fuel structure on pollutant formation was analyzed, and multiple nitrogen-containing intermediate products were detected. A chemical analysis method for aviation fuel combustion was established, and the interaction mechanisms of traditional coal/natural gas with hydrogen/ammonia combustion were revealed.
In the area of high-activity catalyst preparation and application, ZSM-5 zeolite was modified with transition metals such as Ce, Cu, and Cr, significantly enhancing its catalytic performance in propane oxidative dehydrogenation to propylene. Iron/montmorillonite catalysts for acetylene semi-hydrogenation to ethylene were prepared using sol-gel and impregnation methods. Chromium was doped into carbon nanocomposites using chemical vapor deposition (CVD) technology for ethanol conversion to biofuels. LaMnO3 perovskite catalysts were prepared by flame spray pyrolysis, combined with experiments and DFT calculations to explore methane oxidation mechanisms. Through these efforts,the controllable preparation of various metal oxides was achieved.
Patent and Paper
This year, a total of 3 academic papers were published; 7 invention patents were applied for and 3 invention patent authorizations were obtained.
