During the cool flame propagation, HTC autoignition occurs at the hot spot and it induces a hot flame propagating behind the cool flame.
Kinematic stabilization of premixed, freely propagating, ozone-activated, cool flames of dimethyl ether (DME) has been investigated at sub-atmospheric pressure of 7.3 kPa using a laminar flat flame Hencken burner.
The first section of the paper describes the design of unimodal waveguides to enable the AE to propagate to a cool environment where a transducer can be located.
But the point is he could have drawn attention to himself and the subject matter and still managed to achieve the same effect, without propagating the idea that it's cool to prey on teens.
At near-surface levels, faults link with cooling joints and dilational fractures propagating downward from the surface.
The calculation of irradiation on target surfaces is then applied to evaluate the local and overall amount of cooling water needed to prevent the fire from propagating to the surroundings.
The 40Ca+ ions are laser cooled by two laser beams at 397 nm and 866 nm propagating along the trap axis [6].
Fuel coolant reactions may fragment the volcanic material by propagating stress waves, widening cracks and increasing surface area that ultimetly lead to rapid cooling and explosive contraction-driven eruptions.
Differential buoyancy forces the cool gases to move ahead of the flame, which is then extinguished because it is now propagating into a partially diluted nonflammable mixture.
This can be very fast: on a cold, still night, when lake water has been cooled to its freezing point and then slightly supercooled on the surface, it is possible to see ice crystals propagating rapidly across the surface.
