The study of hydrogen explosions in interconnected spaces is essential for safety in industrial and laboratory settings. Due to its highly flammable nature, understanding hydrogen explosion dynamics is essential for risk mitigation. This paper presents an experimental and computational analysis of a hydrogen explosion in a setup with four interconnected chambers. The experimental stand had transparent walls for direct observation. Ignition was initiated to analyze flame propagation, acceleration, and pressure vari...

Propellant powders represent a very important category of explosive substances that enter into the composition of ammunition, with military and civil purpose, in general in all systems where it is necessary to perform a progressive mechanical work. Propellant powders are widely spread in the military field and deflagration is the main form of explosive transformation. Propellant powders, also called colloidal powders, are homogeneous mixtures containing one or more energy-providing substances. Due to their imprope...
