Combustion and Flame, 1959
Abstract Previous work on steady state propagation of flat flames is reviewed and various mathematical techniques are contrasted. In the numerical evaluation of the velocity of uniform propagation of flames, the effects of varying parameters, heat loss and chain reactions are considered, leading to analysis of stability of propagation.

Physics of Fluids
NH3/H2 as a clean fuel exhibits significant application potential. Clarifying its flame evolution characteristics in closed spaces holds substantial value for mitigating explosion consequences under accident scenarios. This study systematically investigates the flame deformation and acceleration mechanisms of premixed NH3/H2/air explosions through ...

The structure of planar and steady premixed flames is controlled by a system of nonlinear reaction diffusion equations. The stiff character of some of the nonlinear reaction terms makes flames different from most of the other reaction-diffusion waves.

Combustion and Flame, 1983
Abstract A simple heat balance has been used to analyze conditions for flame propagation in ducts. A heat flow parameter, coupled with the critical heat flux for ignition, has been used to define the ignition and extent of flame propagation for duct lining materials.

Partially premixed turbulent flame propagation in jet flames
Symposium (International) on Combustion, 1994Flamelet formulations for premixed and non-premixed combustion are combined in order to treat partiallypremixed combustion in the fast chemistry limit. The flamelet concept for non-premixed combustion is based on the equation for the mixture fraction Z (x, t ), while that for premixed combustion uses a field equation for the scalar field G (x, t ...

FLAME PROPAGATION IN LAMINAR BOUNDARY LAYERS
Symposium (International) on Combustion, 1963This paper presents the results of an experimental program aimed at providing a critical test of the equilibrium theory of flame stabilization in boundary layers previously proposed by the senior author. Using schlieren photography and a particle-track technique, the characteristics of a two-dimensional flame stabilized on a cylindrical rod and ...

Flame Propagation in Vertical Channels: Bifurcation to Bimodal Cellular Flames
SIAM Journal on Applied Mathematics, 1984We derive a nonlinear evolution equation and associated boundary conditions which, under certain circumstances, describe downward adiabatic flame propagation in long, vertical channels. We analyze this problem for the case of axial symmetry and show that there exist two critical parameters, the channel radius R and a gravitational acceleration ...

Flame Propagation in Microchannels
2018Combustion at small scales (micro- and mesoscales) is gaining increasing attention these days due to the wide spectrum of potential applications in sensors, actuators, portable electronic devices, rovers, robots, unmanned air vehicles, thrusters, industrial heating devices, and, furthermore, heat and mechanical backup power sources for air-conditioning
