Time variation in the reaction-zone structure of two-phase spray detonations

Abstract

A detailed theoretical analysis of the time-varying detonation structure in a monodisperse spray is presented. The theory identifies exprimentally observed reaction-zone overpressures as deriving from blast waves formed theriin by the explosive ignition of the spray droplets, and follows in time the motion, change in strength, and interactions of these blast waves with one another, and with the leading shock. The results are compared with experimental data by modeling the motion of a finite-size circular pressure transducer through the theoretical data field in a x-t space.
