英文摘要Integrating hydrogen into sustainable energy systems and existing natural gas infrastructures requires fast and reliable prediction of blast dynamics of hydrogen-methane-air mixtures to design effective protective structures. This study proposed an analytical model for predicting blast loading from hydrogen-methane-air (H2-CH4-air) explosions in unconfined spaces, with or without obstacles. The model includes a flame speed prediction formula that accounts for fuel-air characteristics, congestion levels, and fuel quantities, based on extensive experimental data. Modified open-source codes were utilized to calculate the laminar flame properties for the flame speed prediction formula under various initial temperatures, H2/CH4 ratios, and equivalence ratios. Additionally, an empirical model based on theoretical calculations was devised for rapid computation of laminar flame properties. This flame speed prediction formula integrated into the blast loading prediction framework was validated by comparing predicted peak pressures and impulses against diverse experimental results, including scenarios with CH4-air, H2-air, and CH4-H2-air mixtures, both with and without congestion. The application of this model was demonstrated through a case study at Australia's first commercial hydrogen refueling station and another case study for the development of engineering chart for rapid blast loading estimation, illustrating its practical utility in blast loading determination. This research provides an efficient tool for predicting H2-CH4-air blast loading, offering a systematic approach to assess and mitigate the risks associated with vapor cloud explosions in unconfined industrial settings.
