Reacting condensed phase explosives in direct contact
Riccardo Demattè, Louisa Michael, Nikolaos Nikiforakis
In this article we present a new formulation and an associated algorithm for the simultaneous numerical simulation of multiple condensed phase explosives in direct contact with eac…
A unified multi-phase and multi-material formulation for combustion modelling
Maria Nikodemou, Louisa Michael, Nikolaos Nikiforakis
The motivation of this work is to produce an integrated formulation for material response due to detonation wave loading. Here, we focus on elastoplastic structural response. In pa…
Effect of spatial distribution of mesoscale heterogeneities on the shock-to-detonation transition in liquid nitromethane
XiaoCheng Mi, Louisa Michael, Nikolaos Nikiforakis +1
The sensitizing effect of cavities in the form of microbubbles on the shock initiation of a homogeneous liquid explosive is studied computationally. While the presence of voids in…
A multi-physics methodology for four-states of matter
Louisa Michael, Stephen T. Millmore, Nikolaos Nikiforakis
We propose a numerical methodology for the simultaneous numerical simulation of four states of matter; gas, liquid, elastoplastic solids and plasma. The distinct, interacting physi…
Meso-resolved simulations of shock-to-detonation transition in nitromethane with air-filled cavities
XiaoCheng Mi, Louisa Michael, Eleftherios Ioannou +3
Two-dimensional, meso-resolved numerical simulations are performed to investigate the complete shock-to-detonation transition (SDT) process in a mixture of liquid nitromethane (NM)…
Detonation propagation in annular arcs of condensed phase explosives
Eleftherios Ioannou, Stefan Schoch, Nikolaos Nikiforakis +1
We present a numerical study of detonation propagation in unconfined explosive charges shaped as an annular arc (rib). Steady detonation in a straight charge propagates at constant…
