On the mechanisms of pressure generation in vented explosions

Study of Gas Combustion in a Vented Cylindrical Vessel

“…In these methods, pressure variation and venting flow are inferred from calculation of heat, mass, and momentum balances between burned and unburned regions (Canu et al, 1991;Cooper et al, 1986;McCann et al, 1985). However, many key issues remain open to further solutions.…”

“…Besides, relevant experimental data are mostly limited to smallaspect-ratio vessels usually spherical in shape (Cooper et al, 1986;McCann et al, 1985). A special deficiency of experimental observations exists for elongated large-aspect-ratio vessels, which are typical for industrial applications.…”

Uncertainty of the Estimates of Explosion Hazard on the Example of Textile Manufactures

“…A detailed discussion of the role of acoustic flame instabilities in vented gas deflagrations can be found in [43]. Acoustic flame instabilities and enclosure wall linings are important factors in unobstructed, symmetrical enclosures with ignition near the center of the enclosure.…”

“…Some venting models use the surface area of the enclosure as a basis for determining vent area. Analysis of available data [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] shows that such methods overcome certain deficiencies associated with previous methods of calculating vent area.

Propagation of a confined explosion to an external cloud

“…This was identified when designing venting methods for buildings (Cooper et al, 1986, Harrison et Eyre, 1987, Proust et Leprette, 2010. Past experiments (Maxworthy, 1972, 1977, Proust et Leprette, 2010 show that this phenomenon is almost systematic.…”
