3-phonon scattering pathways for vibrational energy transfer in crystalline RDX
Gaurav Kumar, Francis G. VanGessel, Lynn B. Munday +1
A long-held belief is that shock energy induces initiation of an energetic material through an indirect energy up-pumping mechanism involving phonon scattering through doorway mode…

Phonon Lifetimes and Thermal Conductivity of the Molecular Crystal -RDX
Gaurav Kumar, Francis G. VanGessel, Daniel C. Elton +1
The heat transfer properties of the organic molecular crystal -RDX were studied using three phonon-based thermal conductivity models. It was found that the widely used Peierls-B…

A Phonon Boltzmann Study of Microscale Thermal Transport in -RDX Cook-Off
Francis G. VanGessel, Gaurav Kumar, Daniel C. Elton +1
The microscale thermal transport properties of RDX are believed to be major factors in the initiation process. In this study we present a thorough examination of phonon properti…
