针对月球表面部分重力、高真空环境液体排放需求,按照Bond数相似准则,采用内径3.5 mm、长350 mm的透明有机玻璃管弯制成具有3个弯头(弯曲半径约13.5 ~ 17.5 mm) 、一端开口的复杂流道,在地面环境模拟了月面环境复杂管路系统中液体排放过程特征。实验表明,真空环境复杂管道内液体排放过程可以划分为初始状态段、快速减压段、液体排放段、残液排放段和闪蒸终止段5个阶段,各阶段特征可用于更为精细的模型构建,以及相关应用技术验证与性能预测。 |

In order to simulate the characteristics of the process of liquid discharge into high vacuum in the lunar gravity on the moon,a special complex pipeline made of a 350 mm-long transparent organic glass tube with 3 elbows was used in this study. In accordance with the similarity criterion of Bond number,the inner diameter of the pipeline was 3.5 mm in the ground simulation experiment, and thus the length-to-diameter ratio was 100. The bending radius of the 3 elbows was in the range of 13.5 mm to 17.5 mm. One end of the pipe was closed,while the other was open to vacuum. Experimental observations showed that the process of liquid discharge into vacuum could be categorized into the initial state,rapid decompression state,liquid discharge state,residual liquid discharging state,and flashing end state. The characteristics of the two-phase gas-liquid flow patterns observed inside the complex pipeline during each stage could be used for precise modeling of the actual process,as well as for the technology validation of the related applications and the performance prediction. |
