A Numerical Study of Dynamic Detonability Characteristics of Two-phase Unconfined Fuel-Air Clouds
Authors
Abstract
A numerical simulation has been carried out to study the detonability characteristics of two- phase unconfined clouds. The parameters equivalence ratio, turbulence, shape, volume and uniformity of the cloud and the delay time distribution are recognized and introduced as the most important factors determining the reactivity of the cloud and influencing the initiation of a successful detonation. With regard to the dynamic behavior of the cloud and the changes in the magnitude of these significant characteristic parameters, the best ranges of time and position for secondary detonator action are determined.
Comparisons are also performed with experimental results along with theoretical analyses to validate the numerical results obtained in this study.
