为指导潜艇压载水舱排水孔定量设计，探究排水孔通流面积参数与压载水舱吹除压力特性之间的关系，基于RANS模型和VOF模型，以水舱排水孔面积作为单一变量，对高压空气吹除压载水舱的过程进行数值模拟，采用相关性及回归分析的方法，分析水舱内吹除积压随排水孔通流面积变化的规律。计算结果表明，吹除压力和质量流量一定时，压载水舱内壁面最大压力与排水孔面积之间存在负相关的线性关系。研究成果对于排水孔在水舱结构安全和低噪声开孔的约束下开展定量设计具有重要指导意义。
To guide the quantitative design of drainage hole in submarine ballast water tanks and explore the relationship between the drainage hole area and the pressure characteristics of ballast water tank blowing, based on the RANS model and VOF model, the process of high-pressure air blowing out ballast water tanks was numerically simulated with the drainage hole area of the water tank as a single variable. Using correlation and regression analysis methods, analyze the law of the change in the flow area of drainage holes with accumulated pressure in the water tank. The calculation results indicated that there was a negative linear relationship between the maximum pressure on the inner wall of the ballast water tank and the drainage hole area when the blowing pressure and mass flow rate are constant. The research results have important guiding significance for the quantitative design of drainage holes under the constraints of structural safety and low noise openings in water tanks.
