Simulation Analysis of Bubbling Anti-freezing Performance for Ballast Tanks of Ships in Ice Area
By establishing a three-dimensional model of ballast tank,VOF model and solidification melting model were used to analyze the movement law and morphological changes of bubbles in ballast tank.The heat transfer law of seawater-sea ice-bubble multiphase flow in the cabin and the phase change process of seawater-sea ice were explored.The results show that freezing will occur when the tem-perature near the bulkhead drops below the freezing temperature of seawater 273.15K without blowing bub-bles.In the case of bubble blowing,the temperature remains unchanged after it is reduced to 273.15K.
