报告摘要： As alternative approaches, lattice Boltzmann method (LBM) and gas kinetic scheme (GKS) receive more and more attention in recent years. They have their own advantages and disadvantages. To combine advantages of conventional Navier-Stokes solvers, lattice Boltzmann solvers and gas kinetic solvers, and in the meantime, to remove their drawbacks, the lattice Boltzmann flux solver (LBFS) and gas kinetic flux solver (GKFS) were developed for simulation of viscous and inviscid flows. The new solvers are based on Chapman-Enskog expansion analysis, which is a bridge to link N-S equations and kinetic scheme. In the solvers, the macroscopic governing equations are discretized by the finite volume method, where the flux at the cell interface is evaluated by local reconstruction of lattice/continuous Boltzmann solution from macroscopic flow variables at cell centers. The new solvers remove the drawbacks of conventional LBM/GKS and N-S solvers. The proposed LBFS/GKFS is validated by its application to simulate various two-dimensional and three-dimensional stationary and moving boundary flows. The obtained numerical results compare very well with available data in the literature. It demonstrates that LBFS/GKFS can be well applied to simulate various fluid flows with non-uniform mesh and curved boundary.
