摘要:
高压空气吹除主压载水舱系统的性能决定着潜艇事故时的自救能力和轻壳体的吹除安全程度，先进的数值模拟计算仿真方案能够代替无法实现的深水实验，获取气瓶、管道及水舱中的流动特征，为潜艇的设计提供理论支持.采用非定常一维可压缩有摩擦绝热流动理论对气瓶和管道进行计算，得到了吹除过程中的气瓶、管道内的瞬时气体状态参数，并将之作为水舱模拟仿真的进口边界条件；使用欧拉欧拉多相流模型，基于kω的剪切应力输运湍流模型，对压载水舱进行三维非稳态仿真计算，得到了水舱内压力随时间和空间的分布规律、吹除结束时刻舱内气液分布情况等数据.所有计算结果与实际实验结果对比吻合良好，说明了计算方案正确可行.
Abstract:
Properties of highpressure air blowing system in a submarine determine the selfrescue ability in the case of accident and safety degree of light covering blowing.An advanced numerical simulation method can substitute physical experimental method in acquiring flow characteristics in cylinders,pipeline and ballast tanks,which provides theoretical support for the design of submarine.The computing scheme for the system was developed,in which the pipe air flow was considered as an unsteady onedimensional adiabatic compressible flow with friction,and the unsteady gas parameters in the pipeline received from the considering were used as the inlet boundary conditions.The ballast tank was simulated with an EulerianEulerian multiphase model and kω based shear stress transport turbulence model.The pressure distribution over time and space,distribution of gas and liquid in the tank at the end of blowing time and other key data were obtained.The agreement between simulation results and experimental results validates the feasibility and accuracy of the scheme.
