Numerical study on the mechanism of spontaneous ignition of high-pressure hydrogen during its sudden release into a tube

•10-step like opening process is used to mimic the opening process of burst disk.•Hemispherical shock wave is firstly produced and changes into a normal shock.•Spontaneous ignition firstly occurs at the tube boundary.•Numerical results successfully reproduce the experimental results. Hydrogen is reg...
