报告题目:Vector-BGK models based numerical methods and boundary treatments for the incompressible Navier-Stokes equations

报告摘要:We will talk a vectorial LBM and the corresponding boundary treatments for the incompressible Navier-Stokes equations. To begin with, we introduce the discrete-velocity vector-BGK models and give the related models based on numerical methods. Then, we propose a vector-type bounce-back boundary scheme for the vectorial LBM, and analyze the numerical stability of the new boundary scheme by using a subtle structural property of the models. Furthermore, we base on the new scheme and devise a family of parameterized second-order boundary schemes with accuracy independent of the location of the boundary. The accuracy and stability of the boundary schemes above are validated via numerical experiments with both straight and curved boundaries.
