Abstract

Abstract:

For the under?expansion jet generated after the failure leak of high?pressure pipeline, the Birch theory model was used to replace the actual pipeline leak hole with a pseudo?source. Under different conditions of Hydrogen Blend Ratio (HBR), leak hole size and pipeline running pressure, the concentration field distribution, explosion hazard boundary and explosion hazard range of hydrogen?doped natural gas pipelines after leakage and diffusion were studied. The results show that with the increase of HBR, the aggregation of HDNG after leak diffusion is reduced, the explosion hazard range is gradually decreased and the distal hazard is reduced. However, the increase of HBR shifts the position of explosion hazard boundary downward and increases the proximal hazard. With the increase of leak hole size and pipeline pressure, it will increase the influence area of HDNG after leak diffusion, which will move the explosion hazard boundary position upward and increase the explosion hazard range gradually and increase the distal hazard.

Key words: Hydrogen?doped natural gas, Under?expansion jet, High?pressure pipeline leakage, Hydrogen blend ratio, Failure consequences

摘要：

针对高压管道在失效泄漏后产生的欠膨胀射流问题，利用Birch理论模型用伪源代替实际管道的泄漏孔。在不同掺氢比（HBR）、泄漏孔直径、管道运行压力的条件下，研究了掺氢天然气（HDNG）管道泄漏扩散后果区体积分数分布情况、爆炸危险边界、爆炸危险范围的变化规律。结果表明，随着HBR的增加，减少了泄漏扩散后HDNG的聚集，爆炸危险范围逐渐减小，远端危险性降低；随着HBR的增加，爆炸危险边界高度降低，近端危险性增大；随着泄漏孔直径与管道运行压力的增加，泄漏扩散后HDNG的影响区域扩大，爆炸危险边界高度上升，爆炸危险范围逐渐增大，远端危险性增大。
