Therefore in order to know combustion characteristics of these fires, four sort of fire models were examined by Yumoto where four 0.8 m diameter pans (as 1~s(1nner tanks)) existed in a 2.7 m square pan (as a dike) using heptane as f~ell~,'~'. TABLE 3 shows summary of sort of dike fire models and major data.
WebPassive Crown Fire (Intermittent or Persistent Torching) occurs where surface fire intensity is sufficient to ignite tree crowns, individually or in groups, but winds are not sufficient to support propagation from tree to tree. CFB between 0.10 and 0.90. Active Crown Fire occurs where surface and crown fire energy are linked. WebStages of Fire.
