报告内容摘要：

Hypersonic vehicles and re-entry vehicles may encounter flows from the continuum regime to the rarefied regime. Numerical simulation of such flows poses a great challenge in CFD. In this talk, we will firstly describe the existing numerical methods for simulation of continuum and rarefied flows such as DSMC (direct simulation Monte Carlo), DVM (discrete velocity method) and the momentum method. Then our newly-developed Grad distribution function-based gas kinetic flux solver will be presented in details. The developed solver can well simulate continuum flows and rarefied flows with moderate Knudsen number.

Dr Shu Chang is a Professor at the Department of Mechanical Engineering, National University of Singapore. He got his BEng and MEng respectively in 1983 and 1986 from Nanjing University of Aeronautics and Astronautics, China, and his PhD in 1991 from the University of Glasgow, UK. Dr Shu has been working in the computational Fluid Dynamics (CFD) for more than 35 years. His major interest is to develop efficient numerical methods for simulation of various fluid flows. Recently, he developed a series of flux solvers, which are based on the lattice Boltzmann equation and Boltzmann equation. These solvers can be well applied to simulate fluid flows from incompressible regime to hypersonic regime on structured and unstructured meshes. He also made effort to develop some efficient models for simulation of multiphase flows and flows around moving boundaries. So far, he has authored 4 monographs and published more than 380 articles in the international referred journals (SCI indexed). His work has been cited more than 23000 times in Google Scholar.
