摘要/Abstract

摘要： 为了研究高温高压过热液体在意外情况下发生的两相泄漏问题,基于两相泄漏试验平台,采用高速摄影仪和粒子动态分析仪(PDA),分析不同储存条件(储存压力、过热度)和泄漏条件(泄漏口尺寸)下,过热液体储罐泄漏过程中闪蒸射流行为特性。结果表明:闪蒸射流喷射角在泄漏过程中先逐渐增大,然后保持稳定,当罐内过热液体即将完全泄漏时,喷射角将发生突扩,随后迅速减小直至泄漏结束;泄漏过程中,闪蒸射流液滴三维速度随储存压力、过热度及泄漏口尺寸的增大而增大;过热度和泄漏口尺寸越大,液滴粒径越小,液滴粒径随着储存压力增大而增大。

Abstract: Experiments were conducted to investigate the two-phase release of superheated liquid with high temperature and high pressure after accidental releases based on the two-phase release experiment system. The characteristics of flashing jets during the release under different storage and release conditions such as storage pressure, superheat, and nozzle diameterwere studied by high-speed camera and PDA. Results show that the spray angle of flashing jet gradually increases first, then remains stable, and suddenly expands and decreases rapidly when superheated liquid is released completely. Droplets three-dimensional velocities increases with the increase of storage pressure, superheat and nozzle diameter, while droplets diameter decreases with the increase of superheat and nozzle diameter but increases with the increase of storage pressure.

Key words: superheated liquid, high temperature and high pressure, two-phase release, flashing jet, phase Doppler anemometry (PDA)
