Associate Professor Department of Mechanics and Aerospace Engineering

Dr. Lei Wu is an Associate Professor at the Southern University of Science and Technology from November 2019. He received his BSc and MSc in Physics from Zhejiang Normal University, China. After obtaining his PhD in Fluid Mechanics from the University of Strathclyde (UK) in 2013, he continued to work there as a postdoctoral research associate, Chancellor’s Fellow and Senior Lecturer.

His research interest is in Rarefied Gas Dynamics, in particular to construct efficient and accurate numerical schemes to solve the Boltzmann equation for dilute gases and the Enskog equation for dense gas/liquid-vapour multiphase flows, as well as kinetic modelling for polyatomic gas flows, with applications in high-altitude aerothermodynamics of space vehicles, microelectromechanical systems, shale gas transportation in ultra-tight shale strata, granular flows, multi-scale heat transfer in crystals, and thermal motion of quantum gases.
