Experimental and computational analysis of vertical jet fires of methane in normal and sub-atmospheric pressures

Accidental jet fires occurring in industrial facilities can involve severe consequences as they can trigger domino effect. The assessment of the flame-geometry descriptors of the jet can contribute to prevent flame impingement on plant equipment, hence reducing inventory loss and structural collapse...
