火风现象的观测研究和数值模拟

Observation Study of the Fire Wind Phenomena and Numerical Value Simulation

森林火灾过程的火风现象对林火的控制与扑救有着直接的影响。在描述不同火强度引起的环流变化的同 时,根据数值模拟实验.探讨了林火过程中不同阶段火影响区的二维流场和地面火风的特征。

The fire wind phenomenon in forest fire brings a direct effect on the control and suppression of forest fire. This paper describes what the different fire intensities come into being the change of circumfluence based on observation, and probes into planar airflow field of the different phases in fire areas and fire wind characters near to ground on the basis of numerical value simulation experimentation.
