| This study investigates different slopes and wind conditions impact on the fire spread over a pine needle litter at a laboratory scale using fire dynamic simulator. This simulation was performed for different slopes considering both upwind and backwind configurations with a significant wind velocity variation over time. The fuel bed consisted of Pinus halepensis needles with a fixed fuel loading. The predicted fire spread rates were compared with experimental measurements obtained on a sloped combustion bench. The numerical results were consistent with the measured fire spread rates for all slopes and wind configurations, indicating that the model captures the combined effects of slope-induced flame attachment and wind-driven flow on fire propagation. The simulations show that rising slope and favorable wind conditions considerably increase the fire spread rate, however opposing wind slows propagation. These findings validate the numerical approach's capacity to replicate fire behavior over inclined vegetative and offer valuable insights for wildfire modeling, risk assessment, and fire safety engineering applications. |
