Observable characteristics of flashover

open access: yesFire Safety Journal, 2012
Definitions of flashover are multifarious but may be categorized as three types: mathematical, visual and those relying on diction. There are at least two arguments to be had with regard to the definition of flashover: (i) Is rapidity of transition to

Surface Flashover of Silicon

open access: yesEighth IEEE International Conference on Pulsed Power, 1990
The development of high-voltage semiconductor devices has been hampered by the occurrence of flashover at the surface of the semiconductor. The physical mechanisms responsible for this phenomenon are not understood.

Dependence of flashover on assumed value of the discharge coefficient

open access: yesFire Safety Journal, 2001
A non-linear model of flashover, FLASHOVER A1, has been used to explore the dependence of the critical fire size necessary for the onset of flashover on the assumed value for the discharge coefficient, Cd.

Flashover and boundary properties

open access: yesFire Safety Journal, 2010
A non-linear model of flashover, FLASHOVER A1, which has been described in earlier work, has been used to explore the dependence of the critical heat release rate (Qfc) for flashover on the properties of the boundary of the enclosure.
