Classical chemical kinetics in shock physics: Rate constants, order and applications in initiation and detonation

Dear Colleagues,

Please join us for the next edition of the APS Topical Group on Shock Compression of Condensed Matter (GSCCM) virtual seminar series; information on the seminar and how to join are below. We would like to solicit nominations for future seminars and anticipate having a mix of a single speaker or two speakers during an hour time slot. Please email your nominations to Tracy Vogler (tjvogle@sandia.gov). Information on upcoming and past speakers can be found on the APS website; recordings of some past seminars will also be available there.

Classical chemical kinetics in shock physics: Rate constants, order and applications in initiation and detonation
Dr. Bryan Henson
Los Alamos National Laboratory

Work has been ongoing in our group to produce globalized chemistry models of thermal ignition for secondary explosives valid over the entire temperature range of energetic response from thermal ignition by direct heating to detonation. We have made considerable progress recently, resulting in both the first broadly accurate global chemistry models of this type and the possible identification of a crucial component of the chemical mechanism governing the initial decomposition of the crystalline solid. We show that this initial component is based on the condensed phase thermodynamics of the explosive. We further show that it is a common feature of several members of the class of secondary explosives, and may constitute a fundamental, defining aspect of the insensitivity of this family of explosives. In this talk we present models for 1,3,5,7-octahydro-1,3,5,7-tetranitro-tetrazocine (HMX), 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) and 1,3-propanediol-2,2-bis[(nitrooxy)methyl]-tetranitrate (PETN), defined over the temperature range spanning 150 to 2500 C. We will also present a number of applications of these models to problems of ignition, initiation and detonation in these materials.
