Numerical investigation on the effects of current headings on vortex induced motions of a semi-submersible
文献摘要：
In this paper,numerical simulations on vortex-induced motions(VIM)of a semi-submersible at two different current headings are conducted over a wide range of current velocities.The simulations are performed with the computational fluid dynamics(CFD)solver VIM-FOAM-SJTU which is an in-house solver developed based on the OpenFOAM framework.The turbulent flows are resolved with a shear stress transport-delayed detached eddy simulation(SST-DDES)model.Free decay tests for transverse and yaw motion are performed in calm still water to make sure the equivalent stiffness is setup correctly.Then the results of VIM,including motion response,forces and moments,and flow patterns are presented and analyzed carefully.Motions including transverse,in-line and yaw motion at different current headings and velocities are compared.Instantaneous vorticity in the wake regions at different time stamps are also illustrated for different current headings and velocities.
