Summary: I have conducted independent research focusing on emerging technologies and interesting scientific topics, and to resolve imminent engineering problems in aerospace industry. Practical topics I am currently working on are airframe noise and aircraft engine noise related problems. Generally speaking, I tend to balance my research efforts in computational, experimental and theoretical investigations. My background in aeroacoustics and expertise in electronics and information technologies enable me to design and implement specialised measurement technique and array equipments. In particular, I have developed a couple of new measurement techniques for both aircraft engine and airframe noise tests through the extension of compressive sensing and observer theory. I have proposed a theoretical framework that could numerically predict acoustic cloaking performance in turbulent fluids, which could inspire new applications and research directions. This concept was examined with detached eddy simulation and high-order acoustic simulation. I have also studied sound location performance of coiled cochlea using beamforming technology. Most recently, I proposed a theory that could help develop stable solver and liner’s impedance boundary conditions for aircraft engine noise attenuation and prediction. In addition to aeroacoustic research, I have spent part of my time in flow control and flight control and related practical problems I have solved are sonic fatigue issue and flight control design for Chinese hypersonic vehicle projects.
