Analysis of Effects of Stand Density on Wildfire Spread Using Physics-Based Simulation

To analyze the effects of stand density on wildfire spread, physics-based simulations of a flat pine forest were performed while varying tree stand spacing and wind speed. The results from the crown fire transition and subsequent spread stages were collected and analyzed through visual analysis and a comparison of the wildfire spread rates. Overall, strong flame behavior was observed during the transition to a crown fire, which subsequently developed into a quasi-steady propagation. The results
