Structural Design and Simulation of Internal Flow Field Characteristic of Precision Cleaning Vessel for Rocket Engine

  • 摘要: 针对目前火箭发动机精清洗的常用方法,提出了一种60 L清洗容器的设计方法,通过容积计算、外形尺寸计算、强度计算、开孔补强计算、支腿校核计算等,完成图纸的绘制。基于Fluent数值模拟方法,对该清洗容器内流场特性进行仿真,得到全过程可视化压力场云图和速度场云图气液相图。同时,使用多项流模型中的VOF模型,捕捉整个容器内气-液相界面。模拟结果表明,数值模拟的预测与设计要求的预期结果比较一致,说明该设计可行性较高。
