Recently, Prof. Sergei Chernyshenko from Imperial College London and Prof. Zhong Shi from Shanghai Jiao Tong University visited the State Key Laboratory for Turbulence and Complex Systems (LTCS) of Peking University and gave seminar talks on the topic of turbulence.
Prof. Chernyshenko graduated from the Department of Mechanics and Mathematics of the Moscow State University in 1977 and received his Ph.D. and professorship degrees in 1983 and 1995 from the same university. After 20 years at the Institute of Mechanics of the Moscow State University, Prof. Chernyshenko has been a chair professor in the Department of Aeronautics at Imperial College London since 2007. He conducts research in theoretical fluid dynamics. Dr. Zhong Shi is professor in School of Naval Architecture, Ocean and Civil Engineering at Shanghai Jiao Tong University. He was a Senior Visiting Scholar in the Department of Applied Mathematics and Theoretical Physics (DAMTP) and the Isaac Newton Institute for Mathematical Sciences at Cambridge University.
Prof. Sergei Chernyshenko and Professor Zhong Shi gave two academic reports to the teachers and students of the LTCS. Prof. Chernyshenko introduced extrapolating turbulence to higher Reynolds numbers and the bounds for time averages of solutions to equations of fluid mechanics and other dynamical systems.
Prof. Zhong Shi, based on his visiting, teaching, and research experience in the United Kingdom, introduced an overview of the fluid mechanics and turbulence studies of the University of Cambridge, represented by G. I. Taylor and G. K. Batchelor. Then he reported the progress and results of experimental, theoretical and numerical simulations of turbulence in a stable layered two-layer flow.
