Abstract
In this talk, a brief history of CFD development in our research team will be introduced. Starting from COBRAS and NEWFLUME, a 2D free surface model that has a capability of modeling turbulent flows interaction with structures, the team extended the effort to NEWTANK, a 3D two-phase turbulent flow model that can serve as a numerical wave basin to simulate various types of coastal and offshore engineering problems, especially those that involve moving bodies and flexible slender bodies (e.g., cables, vegetation stems and leaves, etc.). The efforts of developing other CFD models and applications to more comprehensive coastal and ocean engineering problems, such as storm surge and urban flood, fish net cage dynamics, etc., will also be briefly introduced. Finally, a recent attempt of further developing NEWFLUME for modeling flexible vegetation will be elaborated. The extended model can accurately capture both the motions of vegetation in waves and the dissipation rate of waves by various types of coastal vegetations.
