摘　　要：文中通过建立压载舱三维模型,采用VOF模型和凝固融化模型分析气泡在压载舱内的运动规律和形态变化,探究舱内海水-海冰-气泡多相流的换热规律以及海水-海冰的相变过程.结果表明:未吹泡情况下舱壁附近温度降低至海水凝固温度273.15 K以下,会发生冻结;吹泡情况下温度降低至273.15 K后维持不变.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 temperature near the bulkhead drops below the freezing temperature of seawater 273.15K without blowing bubbles.In the case of bubble blowing,the temperature remains unchanged after it is reduced to 273.15K.
