โœฆ Synopsis

Abstract

Dust layers on the bottom of mine tunnels, on factory floors, or on the floors of grain elevator passages are the most frequent cause of highly destructive dust explosions. Typically, such layered dust explosions involve a high velocity, accelerating, turbulent flame which is fed by the dust layer and results in high destructive static and dynamic pressures. In some cases transition to detonation has been observed, and such explosions are the most destructive. Scientific studies of such layered dust explosions, conducted at the University of Michigan, are discussed.

This paper presents the results of a computational investigation of the process of deflagration to detonation transition in a combustible gas mixture. The type of combustion (i.e., deflagration or detonation) supported by a two-step reaction scheme is studied as a function of the activation energies

## Extension of earlier worh on the transition ]rom burning to detonution o[ cast explosives shows that the inertia of the confining tube plays a major part in such transition. Tube rupture with pentolite occurs only after a pressure equal to or greater than the shoch initiation pressure has been
