Detonation propagation in weakly confined gases
Youssef K. Wahba, XiaoCheng Mi, Charles B. Kiyanda +1
This study investigates the propagation of detonations along a layered configuration where a reactive gas is weakly confined by a hotter inert layer. CFD simulations are performed…
The ignition of fine iron particles in the Knudsen transition regime
Joel Jean-Philyppe, Aki Fujinawa, Jeffrey M. Bergthorson +1
A theoretical model is considered to predict the minimum ambient gas temperature at which fine iron particles can undergo thermal runaway--the ignition temperature. The model accou…
On the surface chemisorption of oxidizing fine iron particles: insights gained from molecular dynamics simulations
L. C Thijs, E. Kritikos, A. Giusti +4
Molecular dynamics (MD) simulations are performed to investigate the thermal and mass accommodation coefficients (TAC and MAC, respectively) for the combination of iron(-oxide) and…
A Quantitative Analysis of the Ignition Characteristics of Fine Iron Particles
Xiaocheng Mi, Aki Fujinawa, Jeffrey M. Bergthorson
Ignition of iron particles in an oxidizing environment marks the onset of a self-sustained combustion. The objective of the current study is to quantitatively examine the ignition…
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…
Dimensional scaling of flame propagation in discrete particulate clouds
Fredric Y. K. Lam, XiaoCheng Mi, Andrew J. Higgins
The critical dimension necessary for a flame to propagate in suspensions of fuel particles in oxidizer is studied analytically and numerically. Two types of models are considered:…
