摘要

Analyzing the interactions between ice floes and waves is particularly crucial in ice engineering, especially for the environmentally friendly development of the Pan-Arctic area. This paper conducts a study based on computational fluid dynamics (CFD) simulation methods to investigate wave attenuation and the transport processes of ice floes under the interactions between finite block rectangular ice floes and regular waves. The influence of wavelength and wave height on the wave transmission and motion responses of ice floes (both single- and dual- ice conditions) of different sizes and spacing distances ( \(b_g\) ), is thoroughly evaluated by focusing on the overwash phenomenon, wave scattering and surging, and the heaving and pitching of ice floes. Notably, for dual ice floes conditions, a novel ‘overwash transmission’ phenomenon was observed and mitigated or even faded as the \(b_g\) gradually reduced. The \(b_{g}\) not only affected the motion response of the upstream ice floe but also the downstream ice floe significantly, and the wave transmission coefficients. Analyzing key phenomena including floating ice motion response, wave transmission and overwash, and fluid hydrodynamic resonance within multi-ice floes carries substantial practical implications for the design optimization, risk mitigation and operational safety pertaining to ice engineering.
