Advection and Propagation Algorithms

Consider a fluid occupying a domain D with boundary aD, in twoor three-dimensional space. The fluid in a subdomain D, CD is burned, the fluid in D, = D D, is unburned, and the boundary SD, between D, and D, is transported by the velocity of the fluid and also moves with a velocity U in the direction of its own normal; D1 is expanding while D, is contracting. U is the flame speed, and may depend...

Radiation-Affected Laminar Flame Propagation

where ~ = (Kp/rR ) '~ is the weighted nongreyness, K p and r R are the Planck mean and the Rosseland mean of the absorption coefficient, r = rM6 K is optical thickness, r M = (rprR)'/~ the mean absorption, 8 K the conduction flame thickness, P = 4o TM3/(~5 K) the Planck number, T M the adiabatic flame temperature, ~ the thermal conductivity, and w the albedo, the ratio of scattering to extinction.

Bifurcations in non-adiabatic flame propagation models

The study of premixed laminar flames is a central question in combustion theory. Here the differential equations describing steady flame propagation are investigated mathematically. The emphasis is on analytic results, hence a simple model, a onestep exothermic reaction with linear or radiative heat loss is studied. The equations governing our model can be considered as travelling wave equation...

Cyclic flame propagation in premixed combustion

In experiments of hot surface ignition and subsequent flame propagation, a puffing flame instability is observed in mixtures that are stagnant and premixed prior to ignition. By varying the size of the hot surface, power input, and combustion vessel volume, it was determined that the instability is a function of the interaction of the flame, with the fluid flow induced by the combustion product...

Transient flame propagation process and flame-speed oscillation phenomenon in a carbon dust cloud

Please cite this article in press as: L. Qiao, Com A detailed numerical study was conducted to understand the transient flame propagation process and the flame-speed oscillation phenomenon in a carbon dust cloud. The modeling included the solution of a set of time-dependent conservation equations developed for the gas phase and the particle phase in a spherical coordinate. The gas-phase reactio...
