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。
Under extreme conditions of engine combustion technology and fuel diversity is an international hot spot. The National Natural Science Foundation of China held the 92nd “Shuangqing Forum” with the theme of “Key Basic Scientific Problems of Advanced Engine Combustion”. The conference focused on the research status, development trend and challenges in the field of engine combustion based on the three topics of advanced engine, combustion mechanism, combustion measurement and numerical simulation. On the basis of this, the key scientific issues to be solved in this field were summarized , Including combustion chemical reaction kinetics and flame kinetic mechanism, the interaction between combustion and turbulence as well as the basic laws of combustion under extreme conditions and its regulation mechanism, and puts forward some suggestions on the main research topics urgently needed in this field, The future focus on funding direction.
