Development of Next Generation CFD Solver for Numerical Wave Tank
2017 年12 月28 日（星期四），下午16:00
A new CFD approach based on adaptive mesh refinement (AMR) technique, as a next generation CFD solver, is being developed in RIAM, Kyushu University for numerical simulation of strongly nonlinear wave-body interaction problems. The new solver is designed specifically for large scale simulations on the order of 100 million cells. The architecture of the solver will be suitable for systems with large numbers of processors and clusters consisting of multiple compute nodes. Novel schemes, such as CIP, WENO, THINC/SW, MLS-IB etc., are implemented in the solver. The PETSc library is adopted to solve the linear systems. The linear solver is redesigned and modified to satisfy the requirement of the AMR mesh topology. In this presentation, some development details will be presented with newly obtained numerical results.
Changhong Hu is Professor of Research Institute for Applied Mechanics at Kyushu University. He received a B.S. in 1987 and an M.S. in 1990 from Shanghai Jiao Tong University. He received his Ph.D. in Marine Hydrodynamics from Shanghai Jiao Tong University in 1995. From 1995 he served as Assistant, Associate, and Full Professor at Kyushu University. He spent the academic year 2004 as Visiting Associate Professor at Norwegian University of Science and Technology. His research interests lie in the area of computational fluid dynamics and ocean renewable energy technology. Recently he has been involved in several national research projects on offshore wind and tidal current energy developments. From March 2017, he became Shanghai Qian-Ren Guest Professor of Shanghai Jiao Tong University.
