Abstract: High-efficiency de-icing technology is a core focus in ice engineering. In this work, a novel submerged high-pressure water jet de-icing technology was proposed and systematically investigated. Via full-factorial visualized experiments combined with image recognition-based geometric quantification, the effects of jet inlet pressure and nozzle diameter on de-icing performance (depth, width, volume, specific energy) were systematically analyzed. Combined with the evolution of jet deicing contour, the promotional and antagonistic mechanisms of impact crushing and forced convective heat transfer melting were revealed, which clarifies that de-icing mode transition is governed by the spatiotemporal synergy and competition of the two mechanisms. Furthermore, tailored parameter optimization strategies are proposed for typical polar engineering scenarios, providing critical theoretical and experimental support for mitigating ice-structure interaction risks and enhancing the safety of polar navigation and operations.
