报告摘要：

Recent progress toward high-fidelity, high-performance computational fluid dynamics (CFD) solvers for multi-physics and multi-scale simulation of complex flow problems in ship hydrodynamics and other fields will be reported. The first solver employs immersed boundary methods on simple Cartesian grids. Complex fluid-structure interactions including wave-structure interaction problems will be demonstrated. The second solver is extended from the first one and based on orthogonal curvilinear coordinates for resolving the boundary layer and air-water interface at the same time. High-resolution simulations with up to more than 10 billion grid points running on up to more than 10 thousand CPU cores will be showed. The third solver adopts general structured grids for tackling complex geometries in practice applications and is still under development. The code structure and module design will be briefed. Some simple examples will be given for verification and validation. Our contributions to several enabling technologies, including immersed boundary and Cartesian grid methods, level set and fast marching methods, strong coupling schemes for fluid-structure interaction problems, and massively parallel algorithms, will be discussed. Future development directions will be addressed too.
