A numerical study on expansion wave during a leakage in a hydrogen pipeline for leak detection.

Simple model for quick detecting of hydrogen leakage in a pipe focusing on pressure drop as the leakage starts. The model considers different leak diameter, initial pressure, and mass flow rates.一款用于快速检测管道内氢气泄漏的简化模型，其核心聚焦于泄漏起始阶段的压降变化。该模型可适配不同泄漏孔径、初始压力与质量流量工况。
