| Abstract: | Based on the testing result of character of forest fire, with the aid mold of flameextinguishing and mathematical method,
the combustion of the forest fuels and the energy transfer under the convention condition were studied and the mechanism and
interrelated elements of flameextinguishing with high velocity airflow were given. The energy formulae is given: Nz=Kα0 L
0 (15)GH/102
gh
through combustion calculation and test revision. This formula was checked through simulated testing for extinguishing low,
medial and high intensity fires with high velocity airflow. |
