Some developments in premixed combustion modeling

GI Sivashinsky - Proceedings of the Combustion Institute, 2002 - Elsevier
Recent theoretical advances in premixed gas combustion are reviewed. The attention is
focused on (1) self-acceleration of outward propagating wrinkled flames sustained by the …

Mechanisms of detonation formation due to a temperature gradient

AK Kapila, DW Schwendeman, JJ Quirk… - … Theory and Modelling, 2002 - iopscience.iop.org
Emergence of a detonation in a homogeneous, exothermically reacting medium can be
deemed to occur in two phases. The first phase processes the medium so as to create …

Hydraulic resistance as a mechanism for deflagration-to-detonation transition

I Brailovsky, GI Sivashinsky - Combustion and flame, 2000 - Elsevier
A one-dimensional model for premixed gas combustion in a rough tube (or in an inert
porous matrix) accounting for the hydraulic resistance and molecular transport is …

Fast, non-diffusive ignition of a gaseous reacting mixture subject to a pointenergy source

C Vázquez-Espí, A Liñán - Combustion Theory and Modelling, 2001 - iopscience.iop.org
The ignition of a gaseous reactive mixture subject to a localized energy source is analysed
using large activation energy asymptotics. The energy released by the source results in a …

On the transition from deflagration to detonation in narrow tubes

L Kagan, G Sivashinsky - Flow, turbulence and combustion, 2010 - Springer
The paper is an extension of our recent work on the deflagration-to-detonation transition in
narrow channels over the transition in narrow circular tubes under more realistic point …

Thermal-diffusive ignition and flame initiation by a local energy source

C Vazquez-Espi, A Linan - Combustion Theory and Modelling, 2002 - iopscience.iop.org
The ignition and flame initiation in a gaseous reacting mixture subject to a local source of
thermal energy is analysed by means of large activation energy asymptotics. The ignition …

The response of a compressible gas to extremely rapid transient, spatially resolved energy addition: an asymptotic formulation

DR Kassoy - Journal of Engineering Mathematics, 2010 - Springer
An asymptotics-based analysis of the Navier–Stokes equations is used to study the
response of an inert gas volume (the near-field) to localized, spatially distributed, transient …

Response of critical tube diameter phenomenon to small perturbations for gaseous detonations

N Mehrjoo, B Zhang, R Portaro, HD Ng, JHS Lee - Shock Waves, 2014 - Springer
In this experimental study, the critical tube diameter phenomenon of gaseous detonations is
investigated in both stable and unstable mixtures with focus on the failure mechanism. It was …
