Description

Technical Field

[0001] This invention relates to the field of bubble ice breaking technology, specifically to a multi-bubble ice breaking experimental device and method simulating a polar environment. Background Technology

[0002] Currently, research on bubble ice breaking in China is developing rapidly. In the field of single-bubble ice breaking, studies have been conducted on the dynamic behavior of single bubbles under complex boundaries, the mechanism and ability of single-bubble ice breaking, the impact response of single-bubble ice breaking on aluminum plates, and the coupling response of single-bubble ice breaking with structures at multi-angle boundaries. The bubble coupling "slingshot effect" in the field of double-bubble ice breaking is also underway.

[0003] While single-bubble ice-breaking technology has matured and improved, its limitations, such as small jet size, high resource consumption, and weak impact, have led to increased research into dual-bubble and multi-bubble technologies. Currently, in the dual-bubble field, the "slingshot effect" of bubble coupling is the primary research focus. Experimental and numerical simulation studies have revealed that the dual-bubble "slingshot effect" offers advantages over single-bubble technologies, including higher energy output, better environmental friendliness, and lower energy consumption.
