摘要	An unsteady load calculation method for the support configuration of a monopile-supported offshore wind turbine is developed based on the Fluent software platform. Firstly, the water wave is generated by imposing the inlet boundary conditions according to the exact potential flow solution. Then the wave evolution is simulated by solving the unsteady incompressible Navier-Stokes （N-S） equations coupled with the volume of fluid method. For the small amplitude wave with reasonable wave parameters, the numerical wave result agrees well with that of the given wave model. Finally, a monopile support configuration is introduced and a CFD-based load calculation meth- od is established to accurately calculate the unsteady load under the combined action of wave and wind. The com- puted unsteady wave load on a small-size monopile support located in the small amplitude wave flow coincides with that of the Morison formula. The load calculations are also performed on a large-size monopile support and a mono- pile-supported offshore wind turbine under the combined action of small amplitude wave and wind.
