CFD Simulation of a Floating Wind Turbine Platform in Rough Sea Conditions

摘要

In this paper new improvements are presented on development of CFDmodel for simulation of a floating offshore wind turbine (FOWT)platform in large waves and strong winds. The CFD model is aCartesian grid method for multi-phase free surface flows whichcontains a CIP based free surface flow solver, a wind turbine model anda mooring line model. A comparison computation against anexperiment with a semi-submersible type FOWT model has beenperformed for validation of the CFD model. Reasonably goodagreement between the numerical simulation and the experiment hasbeen obtained on floating body motions in large waves.
