THE USE OF COMPUTATIONAL FLUID DYNAMICS TO PROVIDE HIGH RESOLUTION WIND INFORMATION FOR USE IN FIRE GROWTH MODELING.

摘要: I. ABSTRACT Wind speed and direction can have a major influence on fire intensity and rate of spread. Accurate information about local wind flow around a fire perimeter has direct impacts on firefighter safety, allocation of firefighting resources and accuracy of fire intensity and spread predictions. Information currently available to prescribed fire planners and incident management teams is based on local observations, spot weather forecasts or local knowledge and experience. Recent advances in computer technology have resulted in commercially available software programs that can accurately simulate the flow in and around wind driven fires using low cost desktop computers. Here we describe a methodology followed to simulate the flow of air around a fire perimeter burning in complex terrain. The simulations indicate that this technique can provide valuable information about the flow field, providing new …
