Revisiting the minimum ignition energy of hydrogen–oxygen mixtures: Insights from experiment and theory

Case Studies in Thermal Engineering
The minimum ignition energy (MIE) of hydrogen–oxygen mixtures, reported as approximately 1.2 μJ, is over an order of magnitude lower than that of hydrogen–air mixtures, indicating heightened ignition hazards.

Experimental and Numerical Study on the Plasma-Laser-Induced Ignition of Strut Stabilizer at Different Locations

Aerospace
The minimum ignition equivalence ratio of the strut stabilizer is an important parameter in the design of integrated afterburners. The ignition location significantly affects the ignition equivalence ratio and flame propagation, and therefore, it should ...
