“…Additional factors, including turbulent flow characteristics, surface roughness [8,9], temperature and viscosity of the liquid [10], and density and radius of the nuclei [11], may affect cavitation or contribute to its initiation on immersed bodies. Yuan et al [12,13] compared the difference in ice breaking between a non-cavitating and a cavitating water jet, and they found that the collapse of cavitation produces additional pressure loads on the wall, which performs better in the later continuous damage process. Different types of cavitation commonly encountered on ship rudders and on the components of hydraulic systems manifest as sheet-like cavitation, partial cavitation, or cloud cavitation.…”

Experimental investigations were conducted to uncover the impact of cavitation control—through the use of biomimetic riblets on cavitating flows around a circular cylinder. First, the dynamics of cavitation in the flow behind a finite cylinder (without riblets) was unveiled by visualizing the cavitation clouds and measuring the lift force fluctuations acting on the cylinder. Second, in a significant step forward, a comprehensive explanation was provided for the cavitation control methods using two bio-inspired riblet morphologies positioned in different orientations and locations on the cylinder. For the first time, the impacts of these tiny formations on the flow dynamics and the associated cavitation process were scrutinized. This showed that scalloped riblets, with their curved design, induced secondary vortices near their tips and distorted primary streamwise vortices, and that high velocity gradients near the jagged pattern peaks of sawtooth riblets delayed flow separation, which affected cavitation.

“…Consequently, researchers are constantly exploring new meth-ods to improve ice-breaking ability. Many new ice-breaking methods have been proposed, including the use of explosions (Wang et al, 2022), high-pressure air-gun bubbles (Wu et al, 2022;Zhang et al, 2023), high-speed water jets (Yuan et al, 2022;Yuan et al, 2023), moving loads (Zemlyak et al, 2023;Zhou et al, 2023), etc. Among these new ice-breaking methods, breaking the ice by utilizing a moving load has the advantages of high efficiency and cleanliness.…”

Ice-breaking methods have become increasingly significant with the ongoing development of the polar regions. Among many ice-breaking methods, ice-breaking that utilizes a moving load is unique compared with the common collision or impact methods. A moving load can generate flexural-gravity waves (FGWs), under the influence of which the ice sheet undergoes deformation and may even experience structural damage. Moving loads can be divided into above-ice loads and underwater loads. For the above-ice loads, we discuss the characteristics of the FGWs generated by a moving load acting on a complete ice sheet, an ice sheet with a crack, and an ice sheet with a lead of open water. For underwater loads, we discuss the influence on the ice-breaking characteristics of FGWs of the mode of motion, the geometrical features, and the trajectory of motion of the load. In addition to discussing the status of current research and the technical challenges of ice-breaking by moving loads, this paper also looks ahead to future research prospects and presents some preliminary ideas for consideration.
