Kinetic Methods for Multiscale Flows: In Memory of Dr. Peng Wang

About this Collection

Dr. Peng Wang, who passed away on March 2nd, 2022 at the young age of 34, was an Associate Professor in the School of Energy and Power Engineering at Huazhong University of Science and Technology (HUST). Peng obtained his Bachelor of Science in Mathematics from Qingdao University of Technology in 2011, after which he pursued a Master of Science degree in Mathematics at HUST. In 2012, he was selected to join the PhD programme at the State Key Laboratory of Coal Combustion and became a member of our team until 2016 when he received his PhD in Engineering Thermophysics. Peng then began his postdoctoral work in the Department of Mechanics and Aerospace Engineering at the University of Strathclyde. In December 2019, Peng completed his postdoctoral fellowship at the University of Strathclyde and joined the School of Energy and Power Engineering at HUST as an Associate Professor. We are not only losing an exceptional young scholar, but also a dear colleague and friend.

During his short but highly productive professional career, Dr. Wang was a dedicated and hard-working researcher, with over 30 scientific publications to his name. His research focused on the development and application of kinetic models and numerical methods to study multiscale flows. In particular, Peng proposed an extended Enskog-type kinetic model for dense gases with a variable Prandtl number, which offers a computational tractable model for simulating non-equilibrium dense gas flows. He also made significant contributions to kinetic methods, such as Gas-Kinetic Scheme (GKS), Discrete Unified Gas-Kinetic Scheme (DUGKS), and General Synthetic Iterative Scheme (GSIS). Using these advanced numerical tools, Peng further investigated the flow physics of turbulence, gas flows in tight porous media, and oscillatory flows in micro-devices. These achievements made him a prominent and respected scholar among his peers.

Under the invitation of Prof. Kun Xu, one of the Editors-in-Chief of Advances in Aerodynamics (AIA), we have initiated this topical collection to present a snapshot of ongoing research in the field in which Dr. Peng Wang worked. The collection includes five papers by leading experts in the field, covering topics such as a three-dimensional high-order compact GKS, an adaptive DUGKS for all flow regimes, a DUGKS for multiphase flows, a DUGKS for gas mixture flows, and an accelerated low-variance DSMC by GSIS. This collection aims to honour Peng’s contributions to the field and provide readers with a glimpse of the exciting research in this area.

The editor would like to express gratitude to AIA for providing this opportunity and thank all the authors who contributed to this collection.

Dr. Zhaoli Guo is a full Professor in the Institute of Interdisciplinary Research for Mathematics and Applied Science at Huazhong University of Science and Technology (HUST). He obtained his PhD in Scientific Computing from HUST in 2000. His research focuses on numerical methods for multiscale flows and transport phenomena. He is also interested in numerical studies on flows in porous media, non-equilibrium gas flows, phonon and radiation heat transfer, and neutron transport. He has published over 200 scientific papers, and serves as associate editors or editorial board members of several journals, including International Journal of Heat and Mass Transfer, Mathematics and Computers in Simulation, Acta Aerodynamica Sinica, and Chinese Journal of Computational Physics.

  1. The low-variance direct simulation Monte Carlo (LVDSMC) is a powerful method to simulate low-speed rarefied gas flows. However, in the near-continuum flow regime, due to limitations on the time step and spatia...
