Web2. Pool fires . 2.1 Pool Fire Dynamics The structure of most pool fires may be split into a number of fairly well-defined zones: • The liquid fuel itself. In deep pools there may be significant convective flow within the fuel which may affect the fuel vaporisation rate and hence influence the ‘external’ characteristics of the fire. WebNov 22, 2016 · Its specific relationship is concerned with the status of fire plume. The fire plume in this study is assumed to be laminar according to Equation (8), which means that oxygen reaches the flame region mainly by molecular diffusion.
