| 요약 | Due to a complex coupling between a large number of physical and chemical processes that happen over a wide range of length and time scales, our current fundamental understanding of wildland fire spread is limited. Wildland fire spread is affected by many parameters, but two of the most important parameters are wind and slope both of which tilt the flame and plume and bring them closer to the unburnt fuel, which, among other things, increases the convective heat transfer and hence the spread rate. The primary objective of this work is to enhance our fundamental understanding of the effects of wind and slope on the structure of a turbulent, buoyant line fire.To meet the aforementioned objective we perform well-resolved Large Eddy Simulations (LES) of a simplified configuration corresponding to a turbulent, buoyant, methane-fueled, stationary, line fire and subjected to wind or slope. Simulations are performed with an LES solver developed by FM Global and called FireFOAM which is based on the OpenFOAM CFD library.For the cases with wind, the transition from the buoyancy-dominated (in which the flame and plume are mostly detached from the downwind surface and have a tilted vertical shape |
