Risk control analysis of safety accident in Hydrogen refueling station based on PHAST software

This paper uses PHAST software to simulate the hydrogen diffusion distance, explosion and jet fire radiation safety distance of hydrogen refueling station under certain conditions. Comparing the code data and the PHAST simulation results, in special circumstances such as high wind speeds and densely populated areas, it is necessary to increase the distance from the crowd gathering place on the basis of the existing code data, and explain the measures taken by the hydrogen refueling station to prevent leakage accident risks.
