Containing hydrogen deflagrations [PDF]

Journal of Loss Prevention in the Process Industries, 2018
Abstract Schroeder and Holtappels (2005) published data on the explosion characteristics of hydrogen-air mixtures, looking at the effect of pressure and temperature on upper and lower explosive limits and the effect of pressure, temperature, and composition on explosion ratio, PEX/PO.

Research on Perforation Performance and Reservoir Stimulation Effect of a New Self‐Cleaning and Aftereffect Perforation Technology

Geofluids, Volume 2026, Issue 1, 2026.
The development of low‐permeability reservoirs in the South China Sea X Oilfield is frequently hindered by severe compaction damage zones induced by conventional shaped charge perforation, which significantly impair well productivity. To mitigate these adverse effects, novel self‐cleaning and aftereffect perforation technologies have been proposed ...

Analysis of Influencing Factors on Particle Deposition in Electric Heater With Segmental Baffles

International Journal of Chemical Engineering, Volume 2026, Issue 1, 2026.
Against the backdrop of the “dual carbon” goals, electric heaters have been widely deployed on offshore oil and gas platforms. Nevertheless, salt particle deposition inside such equipment severely endangers the stable operation of facilities. Relying on a laboratory dynamic ethylene glycol desalination experimental setup, this paper performs numerical ...

Detonation transition process in a channel equipped with the repeated obstacles (Effect of obstacle height and spacing on the DDT process)

Nihon Kikai Gakkai ronbunshu, 2016
Experiments were performed to investigate the deflagration-to-detonation transition (DDT) process in the channel equipped with repeated obstacles. A premixed gas of hydrogen-oxygen was ignited and the DDT process was visualized by using a high-speed ...

Experimental Investigation of the Enhanced Damage Behavior of Nb17Zr33Ti17W33 HEA Reactive Projectile Impacting Fuel‐Filled Tank

Shock and Vibration, Volume 2026, Issue 1, 2026.
Nb17Zr33Ti17W33 high‐entropy alloy (HEA) is a novel energetic material developed by us, which exhibits non–self‐sustained chemical energy release under high dynamic loading conditions. To investigate the coupling influence between kinetic and chemical energy on damage behavior, we conducted a comparative study of the damage inflicted by Nb17Zr33Ti17W33

Theoretical Evaluation of the Explosion Regimes of Hybrid Mixtures

Chemical Engineering Transactions, 2012
In a previous paper we showed that the theoretical evaluation of the thermo-kinetic parameters relevant to dust explosion (deflagration index; burning velocity and maximum pressure), may be performed by means of detailed simulations of the flame ...

Constraints at a hadronization deflagration front

Physics Letters B, 1989
Abstract Properties of a hadronization front are discussed for the case in which the transition region behaves as a deflagration. As the hydrodynamics of a deflagration front can be determined only after specifying the rate of the phase transformation, we have investigated how the inclusion of the transsition rate equation together with the ...

A Risk Analysis of the Release of Liquid Hydrogen in Road Tunnels: The Effects of Mechanical Ventilation Combined With Geometric and Traffic Characteristics

Risk Analysis, Volume 45, Issue 12, Page 4863-4887, December 2025.
ABSTRACT The transportation of liquid hydrogen (LH2) via road tankers could prove to be the most cost‐effective short‐term option for long‐distance delivery. However, there are significant risks, particularly in confined spaces like road tunnels. An accidental release of LH2 in these structures is likely to create a flammable hydrogen cloud, the ...
