三、時  間:201963日(星期一)上午10:00

四、地  點:研究院大樓202會議室

五、主持人: 李波教授,航空航天學院

六、內容簡介:

This seminar will present recent progress of combustion phenomena at extreme conditions, namely at low-temperature and high-pressure conditions, for advanced energy conversion and propulsion systems. We will first consider the low-temperature chemistry (LTC) affected two-stage autoignition with an emphasis on the LTC-controlled first-stage ignition. Then, the role of LTC in two types of combustion waves, namely subsonic deflagration and supersonic detonation, will be examined respectively. Next, the combustion phenomena at high-pressure, supercritical conditions will be discussed. Different components of real fluids models in the determination of the laminar flame speeds at elevated pressures, namely: equation of state, thermodynamic properties, energy equation, thermal conductivity, mass diffusivity and chemical kinetics will be assessed. The determination and development of detailed reaction mechanisms in supercritical fluids will be presented.  

七、主講人簡介:

Wenkai Liang earned BS degrees in Theoretical and Applied Mechanics and Computer Science from Peking University in 2012 and a PhD degree in Mechanical and Aerospace Engineering at Princeton University in 2018. He is currently a research associate at Department of Mechanical and Aerospace Engineering at Princeton University. His research focuses on theoretical and computational combustion including low-temperature chemistry, analytical methods in chemical kinetics, supercritical flame dynamics, and catalytic combustion. He is the recipient of the George H. Markstein Best Paper Award (2017), Britt and Eli Harrari Fellowship (2017), Meader Fellowship from Andlinger Center for Energy and the Environment (2015) and Guggenheim Fellowship in Aerospace Engineering (2013). He is a Princeton Energy & Climate Scholar at Princeton Energy Institute and a member of the Combustion Institute.
