| 中文摘要: |
| 液体推进剂属于危险化学品，一旦发生泄漏，可能会引起火灾、爆炸、人员中毒、环境污染等后果。因此，有效控制推进剂泄漏，对事故处理和降低危害非常重要。运用FUNENT软件对推进剂贮罐泄漏进行数值模拟，研究泄漏孔位于液面下方时，液体推进剂泄漏到不同液位时的速度分布情况，分析了内压、孔径、孔高以及液体推进剂种类等因素对泄漏后泄漏口速度分布的影响，并将模拟结果与经验公式进行对比分析，验证了模拟结果的准确性。 |
| 英文摘要: |
| Liquid propellants are hazardous chemical that can cause various kinds of accidents during leakage such as fires,explosions, poisoning, and environmental pollution. Thus, effective control of propellant leakage is critical to accident disposal and harm reduction. The CFD software-FUNENT was used to simulate the leakage propellant from storage tank; the distribution of leaking speed was studied under the condition that the leak hole was under the liquid level. The effect of internal pressure, hole diameter, hole height, and the kind of propellant on the velocity distribution of leak hole was analyzed. The results of simulation were contrasted to the empirical formula results, and simulation accuracy was verified. |
