• To investigate the diffusion and combustion phenomena of reactive hydrogen gas leakage when a high-pressure hydrogen tank fails due to crack propagation caused by an initial defect, we have developed a coupled analysis method that simultaneously analyzes the material structure and reactive turbulent multiphase flow through an interdisciplinary research approach. Furthermore, we have developed a new numerical prediction method related to the diffusion flow characteristics and combustion limits of hydrogen leaking due to crack propagation failure of high-pressure tank bulkheads.

We contribute to the design of hydrogen storage containers for various types of transportation equipment and the development of safety guidelines and risk management for hydrogen station configurations.
