摘要：

Experiments of vented gas explosions involving two different cylinder vessel volumes (0.2 and 0.0065 m(3)) were reported. It was found that self-acceleration and larger bulk flame trapped inside the vessel are the main factor enhancing the overpressure attained in 0.2 m(3) vessel. There was about 2 to 7 times increase in ration of pressure and flame speeds on both vessels at the same equivalence ration and K which can be considered as turbulent enhancement factor, beta. Hot spot or auto ignition is responsible to the deflagration to detonation.
