Irradiance of Surface Fire in Forests
This paper discussed the irradiance of fire lines to surface-ground while surface-ground spreading, and the effect of wind speed, slope on irradiance. The formula for calculation of irradiance of fire line to surface-ground was deduced by analysis to flame characteristics and by building up the radiation model of flame zone in fire line. The formula for calculating of irradiance of zone covered flame was deduced by taking the average height of flame as a unit of length and defining the spatial parameters of fire environment--xi, eta, zeta, its radiation field spatial characteristic function--f(xi, eta, zeta). Practical results revealed that the irradiance of fire line to surface-ground is related to flame temperature, fire intensity, flame average height, and the position of observation point. In addition, it is effected also by wind speed, slope. By compare, the irradiance of the sun to surface-ground is negligible during the short period of fire line approached to this area. p4.
