Transmission of an explosion between linked vessels

Temperature and pressure influence on explosion pressures of closed vessel propane–air deflagrations

“…The explosion pressure (defined as the peak pressure developed in a contained deflagration of a flammable mixture) and the explosion time (defined as the time interval from ignition to peak pressure) characteristic for fuel-air gaseous deflagrations in closed vessels, at initial ambient pressure and temperature, were reported in many publications [2][3][4][5][6][7][8][9][10][11][12][13]. Recent data on explosion pressures characteristic of gaseous closed vessel explosions were obtained from experiments in a spherical 20 L vessel with central ignition, as recommended by European standard EN 13673-1 [14].…”

“…Explosion pressures of fuel-air mixtures at pressures and/or temperatures different from ambient were determined in a wide set of conditions (explosion vessels with various forms and volumes; ignition made by local sources with various energies, from a few mJ up to 20 J; position of the ignition source: central or asymmetric) [5,6,10,11,13,[17][18][19][20][21][22][23][24][25][26][27]. The data refer to single fuels, such as hydrogen, methane, propane, propylene or to composite fuels (LPG, gasoline).…”

Explosion pressures of hydrocarbon–air mixtures in closed vessels

“…Explosion pressures and explosion times are important also for calculating laminar burning velocities from closed vessel experiments [33][34][35][36][37][38], vent area design [8,17,27,31,[39][40][41] and characterizing transmission of explosions between interconnected vessels [42][43][44].…”

Confined Kerosene Vapor Explosion: Severity Prediction Laws Based on Numerical Simulations.

“…But the time of transmission between them depends on the initial pressure. 19 Numerous studies also focus on the severity of explosions, which is often linked to the initial fuel concentration 6,21 or to a venting system. 9,12 Several laws are proposed in order to set the dimension of the vent, 12 to estimate the flame speed, 10,16,25 or the external pressure wave.…”
