Numerical Simulation of Diffusion Characteristics and Hazards in Multi-Hole Leakage from Hydrogen-Blended Natural Gas Pipelines

In this study, a 3D model is developed to simulate multi-hole leakage scenarios in buried pipelines transporting hydrogen-blended natural gas (HBNG). By introducing three parameters—the First Dangerous Time (FDT), Ground Dangerous Range (GDR), and Farthest Dangerous Distance (FDD)—to characterize th...
