Complexity of turbulent systems originates from the system nonlinearity and thus the multi-scale interaction. The conventional methods are not effective in characterizing multi-scale physics. With the fast generation of data sources, either numerically or experimentally, it is urgent to develop new tools in data analysis to extract the fundamental physics. In this talk, we focus on the basic principles, algorithm and applications examples of multi-level segment analysis, from which the concepts of scale and structure can be newly understood. Meanwhile, new ideas to study the turbulent flow structure will also be discussed along the line of dissipation element analysis of the scalar field and vectorline segment analysis of the vector field.
Lipo Wang, currently as an associate Prof. at the UM-SJTU Joint Institute, received his Bachelor degree from the department of Mechanical Engineering of Tsinghua Univ. in 1997 and then continued the graduate study since then. In 2002, he joined the Institute of Combustion Science and Technology at the Aachen Univ. (RWTH-Aachen) and then received his Ph.D. degree there in 2007. The main research interests include the fundamental physics of turbulence, especially the flow structure analysis, multi-scale interaction of the complex systems, turbulent flame dynamics and flame modeling. In 2016 Dr. Wang obtained the Best Paper Award of ASME Turbo Expo and in 2007 the Borchers medal for excellent thesis of RWTH-Aachen.
