hello everyone! My name is Yang Dong. I returned to China from Imperial College London in early November 2020 and joined the Department of Mechanics and Aerospace Engineering of Southern University of Science and Technology as an independent PI.
My research focuses on predicting and controlling combustion thermoacoustic instability. The instability of combustion thermoacoustics comes from the positive feedback between sound and unstable combustion: unstable combustion (the actual combustion in the combustion chamber is always unstable due to the existence of turbulence) produces sound, and the sound is reflected by the boundary after being transmitted Come back to further disturb the combustion and produce more sound; this positive feedback process may produce catastrophic great pressure shocks-it is a major technical problem faced in the design of aero engines, power generation/ship gas turbines, and rocket engine combustion chambers. . Predicting and controlling thermoacoustic instability is very challenging because it involves the complex coupling of multi-scale and multi-physical fields between sound waves, turbulence, and combustion-for example, the combustion chamber department of the world’s top aero-engine manufacturer, Rolls-Royce. Use about 80% of the energy to solve the problem. In response to this problem, our research group is committed to developing the world’s most cutting-edge low-order simulation tools and the closely related vortex-acoustic-entropy wave system coupling theoretical model, and combining numerical calculations and experimental measurements to achieve this instability Quantitative prediction and effective control. Our research on the prediction and control of thermoacoustic instability and the theory of vortex-acoustic-entropy wave coupling is at the forefront of the world and has important influence and leading role. Our research results are widely published in top journals in the fields of Acoustics (JSV), Fluid Mechanics (JFM), Combustion (CNF, PCI) and Aerospace (AIAA J.). I was also fortunate to be invited by the top companies in the industry such as Rolls-Royce, Germany, and Reaction Engines, etc. to report on combustion thermal instability and its control.
At present, my laboratory at SUSTech is rapidly being formed, and we will do the most cutting-edge research in the industry with world-class influence here. I sincerely invite all outstanding postdoctoral, doctoral and master students to join us! The research group encourages everyone to actively pursue independence, be brave to challenge difficult problems/authorities, and be good at presenting research results. We are also happy to support everyone to actively participate in academic conferences at home and abroad to carry out exchanges and cooperation.
Postdoc: Candidates should have obtained or will obtain a doctorate degree in related majors in the near future, and have great interest in scientific research (you should have the ambition to become an independent PI within about 3 years), optimistic, focused, and persistent. Research directions include: (1) Theoretical prediction and control of thermoacoustic instability in aero-engine/gas turbine annular combustor, (2) Vortex-acoustic-entropy wave coupling theory. Those with theoretical, numerical or experimental backgrounds are acceptable. Those who have a good mathematical foundation or have a strong interest in learning this knowledge are preferred. (3) Other related issues (can be negotiated). The post-doctorate’s annual salary is about 335,000 yuan (there may be additional year-end awards and housing subsidies); particularly outstanding candidates can apply for outstanding post-doctoral fellows, with an annual salary of up to 415,000 yuan. As the person in charge, he can apply for postdoctoral science fund, national natural science fund, and provincial and municipal funds. Application materials include: (1) One-page personal statement explaining the reasons for applying for this position + (2) Personal resume + (3) Representative papers (not more than three). The application materials are combined into a single PDF file and sent to email@example.com .
Doctoral students : recruit a PhD in mechanics. I hope you have great interest in scientific research itself or in expanding the application of technologies in this field, and are optimistic, focused, and persistent. Those with theoretical, numerical or experimental backgrounds are acceptable, and those who have a good mathematical foundation or a strong interest in learning this knowledge are preferred. Have a master’s degree or will soon obtain a master’s degree Admission adopts the “application-assessment system”, please send your resume to firstname.lastname@example.org .
