摘　　要：以极地运输船为研究对象,借助CFD模拟软件建立压载舱物理模型,探究在压载舱入口流速为0.8~2.0 m/s、颗粒质量流量为0.3~1.0 kg/s时,舱内注入部分海水期间压载舱壁面受到的冲蚀磨损和舱内海水间的对流传热.结果表明:增加入口流速和颗粒质量流量都会加大对压载舱后舱壁处的冲蚀磨损和表面传热.而舱内整体的传热和压载水温度变化主要受进口流速的影响,进口流速越大,舱内海水传热增加,压载水温度随环境下降过程变缓;但进口颗粒质量流量的变化对压载水温度和箱内热流密度的影响不明显.Taking polar carrier as the research object,the physical model of ballast tank was established by CFD simulation software,and the erosion wear of ballast tank wall and convective heat transfer between seawater in the tank were explored when the inlet flow rate of ballast tank was(0.8~2.0)m/s and the particle mass flow rate was(0.3~1.0)kg/s.The results show that increasing the inlet velocity and particle mass flow will increase the erosion wear and surface heat transfer at the rear bulkhead of ballast tank.The overall heat transfer in the cabin and the temperature change of ballast water are mainly affected by the inlet velocity.The greater the inlet velocity,the higher the heat transfer of seawater in the cabin,and the slower the temperature of ballast water decreases with the environment.However,the change of inlet particle mass flow has no obvious effect on ballast water temperature and heat flux in the tank.
