Abstract

This study aims to investigate the influence of wind speed in open spaces on the dispersion behavior of hydrogen clouds formed after the release of liquid hydrogen （LH₂）, as well as the resulting consequences of potential accidents. Using Computational Fluid Dynamics （CFD） software FLACS, we simulated the dispersion characteristics of hydrogen clouds under different wind speed conditions following a LH₂ leak. The research first modeled the physical behavior of LH₂ during the spillage process and subsequently analyzed the dispersion patterns of hydrogen clouds under varying wind speeds. Furthermore, the study assessed the impact of wind speed on the consequences of potential explosion incidents following the ignition of simulated hydrogen clouds resulting from large-scale LH₂ leaks. The results indicate that wind speed is a crucial factor influencing the dispersion and combustion of hydrogen clouds, with its magnitude and direction significantly affecting the stability and explosion range of these clouds. This research provides essential theoretical insights for risk assessment in the storage and transportation of liquid hydrogen and offers scientific guidance for the development of relevant safety measures.
