| 講演： | An immersed boundary method for Navier-Stokes equations on unstructured anisotropic meshes |

| 要旨： | Immersed boundary methods such as penalization present advantages in computational fluid dynamics.They simplify mesh generation and are widely used for moving bodies. However, an issue remains : the treatment of wall boundary conditions. Therefore mesh adaptation can be performed to improve the accuracy of wall treatments. In this work, we propose to solve the penalized Navier-Stokes equations with a residual distribution scheme combined with mesh adaptation. In addition, different ways of tracking an interface are presented to investigate unsteady problems dealing with moving bodies. |
