The dynamics of vented gas explosions
Process Safety Progress, 2010Abstract The results of a large test series on vented gas explosions are herein reported (with vessel sizes ranging from 1 to 100 m 3 mixture of methane, propane, and hydrogen with air). The pressure was not only measured internally but also externally. The flame propagation

Journal of Loss Prevention in the Process Industries, 1996
Abstract Explosion venting technology describes one of the possible constructional protective measures against the effect of explosions. Thanks to the results of extensive explosion trials conducted in the last ten years, important gaps in our knowledge have been filled and new findings gained. Equations involving numerical values have been developed

Explosion venting of bucket elevators
Journal of Loss Prevention in the Process Industries, 2002Abstract This paper is a report of an experimental programme on the explosion protection of bucket elevators by venting. The project was a collaborative effort with funding by the Health and Safety Executive and manufacturers and users of bucket elevators through the British Materials Handling Board.

An update on the European explosion suppression and explosion venting standards
Process Safety Progress, 2002AbstractThis paper sets out the requirements for both explosion suppression and explosion venting according to the draft European Standards that are being prepared under the mandate given to CEN/TC305/WG3, the European Commission and the European Free Trade Association, and supports the essential requirements of EU Directive(s).

Gaseous explosions in vented ducts
Combustion and Flame, 1960Abstract Pentane and propane-air mixtures have been exploded in nine straight steel ducts with openings at one end. The ducts were either of 1 ft square section or of 3 in. or in. diameter circular section and varied in length from 6 to 30 ft. The size of the opening varied within the rang: K = 1 to 64 where K is the ratio of cross sectional area of ...

Prediction for vented explosions in chambers with multiple obstacles
Journal of Hazardous Materials, 2008The predictive ability between existing models on explosion venting, such as the NFPA, Molkov and Yao equations, was examined against experimental data of peak pressures obtained in various chambers with internal obstacles. The NFPA equation yielded the highest overpressures in most cases.

The effect of vent size and concentration in vented gasoline-air explosions
Journal of Loss Prevention in the Process Industries, 2016Abstract Experimental data from vented explosion tests using gasoline-air mixtures with concentrations from 0.88 to 2.41% vol. are presented. A 2L vessel was used for the tests with vent sizes of 25 cm 2 , 50 cm 2 and 100 cm 2 . The tests were focused on the effect of gasoline vapor concentration and vent size on the pressure development and the ...

Thermodynamic Model for Gas Explosions in Vented and Non-Vented Enclosures
Combustion Science and Technology, 2016ABSTRACTA computer model capable of predicting the thermodynamic properties that occur inside a rigid container during both a non-vented or vented gas explosion is described. The model applies the conservation of mass, energy, and momentum of the combustion gases and the motion of a rigid mass that covers an opening to the enclosure. The computer model
