In-situ burning (ISB) is one of the most effective means removing oil spilled over open water. While current ISB practices can eliminate a large fraction oil, they still result in significant airborne emissions particulate matter. ISBs are classified as large, free-buoyant pool fires, from which black smoke consisting matter (PM, soot) emanates plume. An experimental investigation soot fires (P...

Square pool fires with length of 5, 7.5, 10, 15, 20, 25 and 30 cm and rectangular pool fires with dimensions of 10 cm x 20 cm and 10 cm x 40 cm were burned in a wind tunnel, under a longitudinal air flow ranged from 0 to 3m/s with incremental change of about 0.5m/s. Methanol and gasoline were burned and compared, with results indicated that their burning rates showed different response to the l...

Abstract Elevated tree mortality and reduced recruitment of new trees linked to drought fires has been reported across a range forests over the last few decades. Forests that resprout foliage epicormically from buds beneath bark are considered highly resilient disturbance, but potentially at risk elevated mortality, demographic shifts changes species composition due synergistic effects fire. De...

As the main reactor type of fourth-generation nuclear power systems, sodium-cooled fast reactors are now designed and built worldwide. A sodium pool cooling circulation process is indispensable in a reactor. However, fire design basis accidents reactors. The hazard caused by sodium–oxygen reaction safety have attracted extensive attention. Dry powder widely used as an effective fire-extinguishi...

On centennial to millennial timescales fire regimes are driven by climate changes, vegetation composition and human activities. We reconstructed the postglacial vegetation and fire history based on pollen and charcoal data from a small lake in Cradle Mountain National Park and investigated the influence that climate, people, and vegetation had on past fire regimes. In the late-glacial period, a...

Until now, very few works have been devoted to the predictions of the flame structure resulting from the combustion of a vertical burning wall adjacent to a rectangular pool fire at the floor level. This paper describes the application of a three-dimensional model to the prediction of the aerodynamic field and the thermal structure using a finite volume method for solving the fluid dynamic equa...

Recent observations show that the thermal boundary conditions within large-scale fires are significantly affected by the presence of thermally massive objects. These objects cool the soot and gas near their surfaces, and these effects reduce the incoming radiant heat-flux to values lower than the levels expected from simple σTfire models. They also affect the flow and temperature fields in the ...
