Method & Evidence

AimTo compare the ice-breaking effectiveness of underwater explosion bubbles and compressed gas bubbles using a fluid-structure coupling model based on the ALE method.
MethodNumerical Simulation (Computational Modelling)
ProcedureA fluid-structure coupling model was established using the ALE method to simulate the behavior of underwater explosion bubbles and compressed gas bubbles under a free surface. The model analyzed morphological changes, flow loads near a rigid wall, and damage to an ice plate. The number of failed elements in the ice plate was used to assess damage, and optimum standoff distances for both bubble types were determined for a specific ice plate size and energy input.

Strengths & Limitations

Strengths

  • +Provides a quantitative comparison between two icebreaking methods.
  • +Utilizes a sophisticated modelling technique (ALE) to capture complex physics.

Limitations
