A critical first step in responding to an airborne chemical or biological attack is determining the location of the source of the toxin. We have formulated the mathematical description of sourceâ€¦ (More)

An extended Landau-Levieh model of liquid-propellant combustion, one that allows for a local dependence of the burning rate on the (gas) pressure at the liquid-gas interface, exhibits not only theâ€¦ (More)

A theoretical two-phase-flow analysis is developed to describe the quasi-steady propagation, across a pressure jump, of a multi-phase deflagration in confined porous energetic materials. Theâ€¦ (More)

Deflagrations in porous energetic materials are characterized by regions of two-phase flow, where, for sufEciently large flow velocities, temperature-nonequilibration effects can significantly affectâ€¦ (More)

An idealized geometry corresponding to a premixed flame in stagnation-point flow is used to investigate the effects of catalysis on extending the extinction limits of nonadiabatic stretched flames.â€¦ (More)

Hydrodynamic, or Landau, instability in combustion is typically associated with the onset of wrinkling of a flame surface, corresponding to the formation of steady cellular structures as theâ€¦ (More)
