SIAE Lecture Notice: Engine Combustion Instability and its Prediction & Control  

Lecture Title: Engine Combustion Instability and its Prediction & Control    

Keynote speaker: Li Jingxuan, BUAA(Beijing University of Aeronautics and Astronautics)    

Lecture time: May 10, 2019 15:10    

Location: North  Teaching Building 24-101    

    Abstract: Combustion instability control is one of the key technologies in the development of aerospace engines. Under the conditions of high temperature, high pressure and high-energy density, the coupling of flow, combustion and acoustic disturbance are very likely to occur, leading to the rapid pulsation of combustion chamber pressure and heat release, causing the ablation and even explosion of engine components. However, due to the high complexity of the interaction between flow, combustion and acoustic disturbance, the mechanism understanding and predictive control of combustion instability have great challenges.The keynote speaker will introduce the research status and direction of combustion instability at home and abroad, and introduce in detail some methods of combustion instability prediction and control of the applicant's team.

Profile of the lecturer: Dr. Li Jingxuan is currently a professor and doctoral supervisor at the Aerospace Propulsion Department of the School of Aerospace, Beijing University of Aeronautics and Astronautics.Dr. Li Jingxuan graduated from Beijing University of Aeronautics and Astronautics with a master's degree. During his Ph.D., he invented two methods for measuring the pulsation of unsteady combustion heat release rate.After pursuing a postdoctoral degree at Imperial College London from 2013 to 2017, he was mainly engaged in combustion instability prediction and control research.In September 2017, he was employed by Beijing University of Aeronautics and Astronautics.Mr. Li Jingxuan's main research direction is aerospace engine combustion instability measurement, prediction and control. He had published more than 20 academic papers in related fields, many of which were published in distinguished journals such as "Combustion and Flame", "Journal of Sound and Vibration" and "Fuel", etc.

Teachers and students are welcome to attend.
