Study on the effect mechanism of CO on gas explosion reaction

open access: yesGong-kuang zidonghua, 2022
At present, most of the research on gas explosion takes the mixed gas of CH4 and air as the research object, but the gas explosion in coal mine is not a separate CH4 explosion, there are often CO and other components, which have a certain effect on gas ...

Explosion simulation of pressurized components

open access: yesRakenteiden Mekaniikka, 2017
This article describes one simulation study of engine components that operate in an explosion risk zone. High pressure system failures and unfavorable chemical reactions put components in situations not commonly considered in normal dimensioning. From the safety point of view, explosion and damage control involve a wide range of uncertainty factors.
