Professor Chao Sun

The Physics of Flowing Dense Emulsions in Wall-Bounded Turbulence
Abstract:
Turbulent emulsions are ubiquitous in chemical engineering, food processing, pharmaceuticals, and other industries. However, our understanding of these systems remains limited due to the multiscale nature of turbulent flows and the presence of extensive interfaces, which pose significant challenges for both experimental measurements and numerical simulations. In this talk, we present recent studies on emulsions in wall-bounded turbulent Taylor-Couette flow, focusing on the statistics of the dispersed phase and the global momentum transport of the system. We also discuss new measurements of local velocity statistics in the continuous phase of turbulent emulsions at high dispersed-phase volume fractions, made possible by precisely matching the refractive indices of the two phases. Finally, we examine catastrophic phase inversions, which occur when the volume fraction of the dispersed phase exceeds a critical threshold during dynamic emulsification.

Chao Sun is a Professor at Tsinghua University, affiliated with the Center for Combustion Energy, the Department of Energy and Power Engineering, and the School of Aerospace Engineering. He also holds a part-time professorship at the University of Twente in the Netherlands. Dr. Sun received his PhD from the Chinese University of Hong Kong in 2006. He was a faculty member at the University of Twente from 2009 to 2015 and joined Tsinghua University as a Full Professor in 2015. His research focuses on multiphase flows, turbulence, bubbles and droplets, and heat and mass transfer. Dr. Sun is a Fellow of the American Physical Society, a recipient of the Xplorer Prize, and a New Cornerstone Investigator. He served as a member of the Governing Board of the International Conference on Multiphase Flow and on the committee for the APS-DFD Frenkiel Award. He is currently an Associate Editor of Physical Review Fluids and a member of the editorial boards of Experiments in Fluids, Acta Mechanica Sinica, and other journals.
