Dr Zhengtong Xie is Associate Professor (Senior Lecturer) within Engineering and Physical Sciences at the University of Southampton.

Zheng-Tong Xie’s expertise is in Aerodynamics and Computational Fluid Dynamics (CFD), with a focus on large eddy simulation applied for various physical and application areas.

He is currently Senior Lecturer in the Aerodynamics and Flight Mechanics (AFM) research group. He is also currently a member of the UK National Centre for Atmospheric Science (NCAS) and the Principal Investigator of Urban CFD project at the University of Southampton.

Zheng-Tong Xie studied for a Bachelor degree in Engineering Mechanics from 1986-1990 at Shanghai Jiao Tong University (SJTU).  He did his Masters degree in Aerodynamics in 1990-1992 (thesis: A numerical simulation of the unsteady response to a gust for a wing-tail combination) and a PhD in Hydrodynamics from 1992-1995 (thesis: Numerical simulations and water tunnel experiments for modelling hydrodynamic characteristics of cavitating axisymmetric bodies at small angles of attack), both at SJTU.  He moved to Beijing to work as a Post Doctoral Researcher and was then promoted to Associate Professor at the Institute of Mechanics, Chinese Academy of Sciences, working on Large Eddy Simulations for Environmental Flows (1995-2000).  He has been continuing working on Large Eddy Simulations for Environmental Flows and Wind Engineering Problems since then.  From 2000 to 2004 he took up a position as Research Fellow in the University of Surrey.  He moved to Southampton as a Senior Research Fellow in 2004.

Research interests

  • Large-Eddy Simulation for flow, scalar dispersion and heat transfer over a group of bluff bodies.
  • Modelling interaction of fluid and slender structures, e.g. long-span bridges, high-rise buildings, large wind-turbine blades
  • Coupling between large-scale geophysical flow and small scale turbulent flow, e.g. weather scale flows and street scale flows.
  • New approaches (e.g. inflow boundary conditions, near-wall treatment) for Large-Eddy Simulations; hybrid LES.
  • Thermal stability of urban boundary layer and its structure.
  • Wind turbine flows.
