| 摘 要： | 本文应用FAC2程序,通过数值计算的方法,模拟了森林野外火区上的浮力流动随火区参数及环境气象因素的改变而变化的情况。我们考虑的火区因素有:人口速度、人口温度、及火区尺寸,考虑的环境气象因素有:大气静力稳定度和侧风。作者较为系统地计算了一些算例,通过这些算例可以初步给出森林野外火中,火区上的浮力流动与火区参数及这些气象因素关系的粗略图像。

| Abstract: | This paper simulates the buoyant flow changed with the parameters of fire and situation of surroundings atmosphere. We compute it with numerical method by using the FAC2 program. The fire region parameters are: input velocity, input temperature and the length of fire region. The environment meteorology parameters are: the steady degree of atmosphere statics force and the side wind. The authors compute some examples and can roughly give the image of the relation between the buoyant flow and the parameters of fire and the situation of surroundings atmosphere. |
