摘要
The heave and pitch motions of an ice floe in regular waves are studied for different wavelengths with a fixed wave height to understand the interaction between waves and ice floes in the marginal ice zone. Overwash caused by waves is simulated and its impact on the floe motion is investigated. The motion response of floes subjected to overwash and those not subjected to overwash is compared. In this paper, a three-dimensional numerical wave tank (NWT) is established using computational fluid dynamics (CFD) technology. By imposing a specified velocity condition on the inlet boundary, the wave is generated. The finite volume method (VOF) is used to solve fluid governing equations. The floe motion is modeled by an overset grid. Meanwhile, the resultant force and resultant moment of the fluid acting on the floating ice are calculated, and the equations of the ice motion are solved to update the floe motion. The results show that the effect of overwash is more pronounced when the wavelength is small; that is the ice motion is significantly suppressed. The applied numerical model could provide valuable information for Arctic engineering purposes. © 2021, Editorial Department of Journal of HEU. All right reserved.
