Comparison of empirical and semi-empirical calculation methods for venting of gas explosions

Explosion parameters of methanol–air mixtures

“…The maximum explosion pressures, the maximum rates of pressure rise, the explosion delay time and the deflagration index are important values for vent area design [34,35], for the explosion protection measure ''constructive explosion protection'' [33] and for the characterization of explosion transmission between interconnected vessels [36,37] methanol-air mixtures in a wide range of initial conditions are needed for extending databases of explosion parameters of fuels.…”

The rate of pressure rise of gaseous propylene–air explosions in spherical and cylindrical enclosures

“…Besides the explosion pressure, the maximum rate of pressure rise is one of the most important safety parameters for assessing the hazard of a process and for design of vessels able to withstand an explosion or of vents used as relief devices of enclosures against damages produced by gaseous explosions [2][3][4][5].…”

Vent burst pressure effects on vented gas explosion reduced pressure

“…The prediction of the reduced explosion pressure, P red , required for the design of explosion vents (Bradley and Micheson, 1978aand 1978b, Razus and Krause, 2001 does not have a specific methodology for predicting the effect of the vent static pressure, P stat . Explosion venting theories also have empirical constants, often referred to as turbulence factors, accounting for vent static pressure effects for theories that apply to free venting.…”
