Abstract.

The macroscopic governing differential equations in fluid mechanics can be discretized by the finite volume method (FVM), and the conservative flow variables at cell centres can be given from the solution of discrete governing equations. In the solution process, we need to evaluate numerical fluxes at cell interfaces from the solution at cell centres. Currently, there are two kinds of approaches to reconstruct the solution for evaluation of numerical fluxes. One is mathematical approach, which is based on smooth function approximation. The other is physical approach, which is based on the solution of governing equation or simplified governing equation. A good example in this category is the Riemann solver, which is based on solution of one-dimensional Euler equation. In this talk, a brief review of current flux solvers will be presented first. Then the newly-developed lattice Boltzmann flux solver and gas kinetic flux solver will be shown in details. These solvers evaluate viscous and inviscid fluxes simultaneously and physically. They combine advantages of conventional Navier-Stokes solvers and lattice Boltzmann/gas kinetic solvers. The fluid flows from incompressible regime to hypersonic regime can be well simulated by these solvers. The proposed new flux solvers will be validated by various numerical examples.

报告人简介:

Dr. Chang Shu 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 to solve heat transfer and fluid flow problems, which are governed by a set of partial differential equations. 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. Currently, he is the Chief Editor of a book series for Advances in Computational Fluid Dynamics, the Chief Editor of Advances in Applied Mathematics and Mechanics, Associate Editor of International Journal for Numerical Methods in Fluids, and editorial board member of several international journals.
