Experimental study on shock wave propagation and spontaneous ignition induced by high-pressure hydrogen suddenly released into T-shaped tubes
Zhilei Wang,Zhilei Wang,Xuhai Pan,Yiming Jiang,Qingyuan Wang,Yunyu Li,Jianjun Xiao,Thomas Jordan,Juncheng Jiang +8 more
TL;DR: In this paper, a series of experiments were conducted to investigate the influence of bifurcation structure in tubes on the spontaneous ignition of high-pressure hydrogen, and the results showed that the T-shaped structure has a significant influence on the occurrence of spontaneous ignition.

Effects of the arc-shaped corner on the shock wave and self-ignition induced by sudden release of pressurized hydrogen
TL;DR: In this paper, the authors investigated the shock wave and self-ignition induced by high-pressure hydrogen release via three 90° arc-shaped tubes and found that reflected shock waves generated in the bend would spread both upstream and downstream.

Numerical study on the flow characteristics of pressurized hydrogen leaking into the confined space through different shaped orifices
Tao Zhang,Yiming Jiang,Shiqi Wang,Xuhai Pan,Min Hua,Zhilei Wang,Qingyuan Wang,Yunyu Li,Juncheng Jiang +8 more
TL;DR: In this paper , the authors used the three-dimensional Large-Eddy Simulation (LES) model to simulate high-pressure hydrogen leakage in a confined space and investigated the effects of the leakage hole shape on the flow features, including the circle, square, and triangle.

Effects of tubes with different inlet shapes on the shock wave and self-ignition induced by accidental release of pressurized hydrogen
Tao Zhang,Yiming Jiang,Xuhai Pan,Zhilei Wang,Qing Wang,Yunyu Li,La Ta,Min Hua,Juncheng Jiang +8 more
TL;DR: In this article , the self-ignition of pressurized hydrogen discharged into tubes with different inlet shapes was studied experimentally, and the results showed that the range of the pressure dead zone grows with increasing release pressure, which is not conducive to the occurrence of autoignition.

Experimental investigation on spontaneous ignition caused by pressurized hydrogen suddenly release into an S-shaped tube
TL;DR: In this article, an experimental investigation on the effects of continuous semicircular curved structure on spontaneous ignition during pressurized hydrogen suddenly release was conducted, and an S-shaped tube with 700mm in length and 10mm in diameter was used in their experiments, and a straight tube with the same configuration was adopted for comparison.
