中文摘要：

以FLUENT软件为平台建立二维数值模型,对＂点头鸭＂在不同攻角不同来流速度下的稳态绕流进行了数值模拟。本文模拟得到了不同攻角和来流速度下＂点头鸭＂受到的波浪力,以及相同攻角下＂点头鸭＂在不同来流速度时的速度场,并进行了分析和对比。所得结论可为开发利用高效飘浮式波浪能发电装置提供理论依据。

英文摘要：

Two-dimensional numerical model of the flow around a＂nodding duck＂ has been made based on the platform of FLUENT software,and the steady-state flow at different angle of attack and different flow velocities has been investigated by numerical simulation.In this paper,the wave force of ＂nodding duck＂ in different attack angle and the flow velocities has been simulated,and the same angle of attack ＂nodding duck＂ in different flow velocity the velocity field are also gained and compared.The conclusion can be useful to develop and utilize the high efficiency floating type of wave power device.
