先进发动机燃烧基础研究的进展和关键科学问题

Progress and Key Scientific Issues on Advanced Engine Combustion Research——Summary of the 92^(nd) Shuangqing Forum of NFSC

极端条件下的发动机燃烧技术以及燃料多样性是国际上的研究热点。国家自然科学基金委员会召开了以"先进发动机燃烧关键基础科学问题"为主题的第92期"双清论坛"。会议围绕先进发动机、燃烧机理研究、燃烧测量与数值模拟等3个专题深入探讨了发动机燃烧领域的研究现状、发展趋势及面临的挑战,在此基础上凝练出了该领域需要解决的关键科学问题,包括燃烧化学反应动力学和火焰动力学机理、燃烧与湍流的相互作用以及极端条件下燃烧的基本规律及其调控机制等,并就该领域未来急需开展的主要研究内容提出了建议,研讨了今后的重点资助方向。

Combustion technology of engines under extreme conditions and fuel diversity has been the re- search hot topic in the international community. The National Natural Science Foundation of China recently held the 92na Shuangqing Forum themed as ＂Key Fundamental Scientific Issues on Advanced Engine Com- bustion Research＂. Focused on three special topics, namely advanced engine, combustion mechanism re- search, and measurement and numerical simulation of combustion, the current research status, future de- velop tendency, and faced challenges on engine combustion field were discussed thoroughly. Based on these, key scientific issues in these fields that need to be resolved were addressed, including the mechanism of combustion chemical kinetics and flame dynamics, the interactions between combustion and turbulent flows, and the fundamentals as well as the control mechanism of combustion under extreme conditions. Meanwhile, the main future research context and funding directions in the field were suggested.
