“…It could assume that the general tendency of the data of Koseki et al (the scaling to D 0.5 ) is due to the larger pool diameters employed. In the same time, the lower range of the pool size range investigated by Chatris et al [31] overlaps the upper range of pools in the experiments of Koseki et al [8]. The former can be clearly defined as a thin-layer boilover.…”

“…6(a)). Thus, it could suggest that the heat conduction across the fuel dominates for smaller diameter pool fires and the scaling corresponds to the case B, while for D = 0.3-5 m pools the heat absorption starts to dominate and the scaling approaches the case C. The increase of pool diameter shifts the heat transfer controlling mechanism and all the data scale of Koseki et al [8] and those of Chatris et al [31] scale t D ∼ √ D, thus confirming the prediction done for the Case C (see Eq. (47b)).…”

“…On the other hand, for relatively thicker fuel beds [8,20] The large pool diameters within the range of 1-10 m (the experiments of Chatris at al. [31] and more that 100 m, like in the case of oil spills) are usually related to thin fuel layers that yield y 0 ≡ O(10 −2 ). This leads to a source term of (18) of order of O(1).…”

The paper concerns the heat transfer models of liquid fuel bed burning on water sublayer. The main efforts are stressed on the qualitative assessment of models available and their adequacy as well as on the prediction of the boilover onset. The analysis employed various data obtained by different research groups. The evaluation of the suitable functional relationships predicting the pre-boilover time was done based on dimensionless groups derived from two types of models published in the literature: Surface Absorption Models and In-Depth Absorption Models.

a b s t r a c tTo examine the pressure effect on burning rate, flame height and axial temperature distribution of diffusion fires, experimental measurement and theoretical analysis on circular n-Heptane fires with serial sizes were conducted at two altitudes, i.e. 100.8 kPa (in a sea-level city Hefei) and 64.3 kPa (in a Tibetan city Lhasa). From the results, the mean burning rate at quasi-steady stage and boiling stage consistently with the correlation coefficients derived from the current low-pressure measurements. Analysis shows that the flame height and the plume temperature increase with the pressure rise as a power function of pressure for the same pool size.

“…Fuel evaporation rates from large liquid pool fires have been studied for several decades (see Hottel [1959], Babrauskas [1983], Koseki [1989], Koseki and Mulholland [1991], Koseki and Iwata [2000], Chatris et al [2001], and Muñoz et al [2004]). Fuel regression rates show a dependence upon fire diameter, fuel type, and ambient conditions including temperature and wind speed.…”

As the capabilities of numerical simulations increase, decision makers are increasingly relying upon simulations rather than experiments to assess risks across a wide variety of accident scenarios including fires. There are still, however, many aspects of fires that are either not well understood or are difficult to treat from first principles due to the computational expense. For a simulation to be truly predictive and to provide decision makers with information which can be reliably used for risk assessment the remaining physical processes must be studied and suitable models developed for the effects of the physics. The model for the fuel evaporation rate in a liquid fuel pool fire is significant because in well-ventilated fires the evaporation rate largely controls the total heat release rate from the fire. A set of experiments are outlined in this report which will provide data for the development and validation of models for the fuel regression rates in liquid hydrocarbon fuel fires. The experiments will be performed on fires in the fully turbulent scale range (> 1 m diameter) and with a number of hydrocarbon fuels ranging from lightly sooting to heavily sooting. The importance of spectral absorption in the liquid fuels and the vapor dome above the pool will be investigated and the total heat flux to the pool surface will be measured. The importance of convection within the liquid fuel will be assessed by restricting large scale liquid motion in some tests. These data sets will provide a sound, experimentally proven basis for assessing how much of the liquid fuel needs to be modeled to enable a predictive simulation of a fuel fire given the couplings between evaporation of fuel from the pool and the heat release from the fire which drives the evaporation.
