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, C-d. It has been found
that, overall, there is a significant dependence on C-d. Experiments should
be conducted in order to determine empirically the values of discharge coe
fficients for different cases. (C) 2001 Elsevier Science Ltd. All rights re
