讲座一：Combustion: A Key Player in Transitioning to Low Carbon Renewable Energy
报告人：Prof. Yiguang Ju
This lecture will discuss the critical role and potential of advanced combustion in a carbon constrained world. Firstly, we will discuss the recent advanced technologies and concepts of electricity and power generation to drastically improve energy efficiency and reduce carbon emissions. The concept of using hydrogen produced from excess renewable electricity and low energy content biogas for fuel and load flexible low carbon power generation will be introduced. High pressure oxy combustion and supercritical CO2power generation cycle will be discussed. Secondly, the technology development of advanced internal combustion engines with fuel and engine co-optimization will be presented. Challenges of ignition, emissions and knocking control of low temperature combustion will be analyzed. Opportunities and challenges of fast fuel screening, predictive kinetic mechanism, and computational tool development as well as advanced laser diagnostics and plasma assisted combustion control will be summarized.
讲座二：Plasma Assisted Combustion: Progress and Challenges
报告人：Prof. Yiguang Ju
In this lecture, the recent progresses in plasma assisted combustion, in-situ mid-IR diagnostics, and studies of low temperature plasma combustion kinetic mechanism are discussed. The observations of plasma activated direction ignition to flame transition, cool flames, and mild combustion are presented. The direct measurements of intermediate species and the kinetic pathways of low temperature ethylene/methanol oxidation in a non-equilibrium plasma reactor and a photolysis reactor are reviewed. The validity of low temperature plasma combustion kinetic mechanism is discussed. The recent development high pressure kinetic mechanism for plasma assisted combustion and technical challenges for future research are summarized.
