Propagation law of gas-coal dust explosion shock waves under different explosion conditions

Gong-kuang zidonghua
To address the limitations of current experimental and numerical studies on the propagation of gas-coal dust explosion shock waves, which are mostly confined to small-scale laboratory pipelines or local roadways, this study adopted a segmented relay ...

Overpressure Generation Mechanism in the Jurassic Formations of the Fukang Sag, Junggar Basin: Its Significance for Deep Petroleum Exploration

Geosciences
The Jurassic reservoirs in the Fukang Sag of the Junggar Basin exhibit heterogeneous overpressure. As the mechanisms underlying overpressure generation remain poorly constrained, this poses challenges for accurate pre-drilling-pressure prediction and ...

Blast Wave Generated by Delayed Ignition of Under-Expanded Hydrogen Free Jet at Ambient and Cryogenic Temperatures

Hydrogen, 2022
An under-expanded hydrogen jet from high-pressure equipment or storage tank is a potential incident scenario. Experiments demonstrated that the delayed ignition of a highly turbulent under-expanded hydrogen jet generates a blast wave able to harm people ...
