Abstract

This study explores how Computational Fluid Dynamics (CFD) modeling predicts and mitigates safety risks from hydrogen leaks at hydrogen refueling stations (HRS). Three-dimensional simulations were performed using PHAST Standalone 9.1 software to evaluate hydrogen dispersion under wind speeds of 1, 2, and 5 m/s. The results identify critical risk factors and potential gas accumulation zones. Based on the dispersion patterns, this paper proposes strategic locations for safety equipment, including gas, acoustic, and flame detectors. This proactive modeling approach provides valuable design guidelines to enhance facility safety before real-world deployment.
