At higher temperatures this decomposition is self-accelerating.
We show that the char oxidation reaction hardly affects the characteristics of smolder wave propagation due to its small reaction rate, though under appropriate conditions, it can act as the trigger for the transition to flaming due to its ability to self-accelerate.
The rf discharge induced a dc self-bias accelerating ions towards the growing film during the whole deposition process.
Radiation effects on the propagation speed and acceleration exponent of the large-scale self-accelerating spherical flame are assessed.
This novel self-accelerating pulse is somewhat similar to but never the same as the Airy one.
Over the past several years, spatially shaped self-accelerating beams along different trajectories have been studied extensively.
We found that the produced sulfide promoted the formation of more polysulfide, which enabled a self-accelerating chain reaction of sulfur reduction via polysulfide.
Particularly, the smallest average particle size 70.9 μm was the most sensitive with self-accelerating temperature 200.6 °C, critical ignition temperature 201.8 °C, and thermal explosion temperature 203.1 °C.
A novel self-accelerating pulse whose shape and spectrum consist of one main lobe and a series of weak decayed side ones is revealed numerically by a hyperbolic-secant soliton pulse with the cubic temporal phase (CTP).
Specifically, we first demonstrate that the propagation speed of the self-accelerating cellularly unstable flames at various pressures, including the state of the critical radius at which the flame becomes unstable, can be collapsed by plotting the flame speed, normalized by the planar flame speed, versus the normalized radius, or the Peclet number.
LF, a concept which we introduced, is the distance that a steadily propagating smolder wave must travel inside the porous sample before the char oxidation reaction, which hardly affects the characteristics of the smolder wave itself, spontaneously self-accelerates, resulting in an eruption of the temperature in the smolder front.
