Sentence examples for flame growth from inspiring English sources

Spark-ignited flame growth is a common engineering application in which the role played by flow turbulence is as important as the combustion chemistry.

The period of flame growth is prolonged with decreasing sample spacing and finally, at a small enough sample spacing, the flame distance keeps increasing until the flame disappears.

However, the local instabilities and turbulence levels are so high during the first stages of the dispersion that the flame growth can be disturbed for short ignition delays.

This paper presents a simple planar model for this process as a means to relate the dynamic flame growth to the resulting overpressure.

In the three-dimensional configuration with the spot ignition, the flame growth in the direction perpendicular to the flow is significantly enhanced by the confinement effects.

Several examples, in both forced and buoyant flows, are shown to illustrate the model capability to predict flame growth and extinction processes.

The combustion phenomena accounted for by the correlation include: turbulence generated by the flame front itself; leading point mechanism stemming from the preferential diffusion of hydrogen in air in stretched flames; growth of the fractal area of the turbulent flame surface; initial turbulence in the flammable mixture; as well as effects of enclosure aspect ratio and presence of obstacles.

The correlations obtained can be used to predict activation times of in-rack sprinklers and they can be incorporated into engineering models designed to predict flame spread and fire growth in storage geometries.

Pyrolysis is the thermochemical process that leads to the ignition of a solid fuel and a key mechanism in flame spread and fire growth.

The images showed that the flame always preserved its shape while growing in size (even when it had been initiated with a highly convoluted shape); image processing demonstrated the manner with which the flame-growth speed varied as the flame propagated and approached the pentroof and piston-crown walls for slow, "typical" or fast burning cycles.

The flame kernel growth rate is high when the ignition probability is high for all parameters, except for jet velocity.
