该文介绍了野外火火头前方气流速度场和温度场在不同火强度、坡度和环境风速条件下的规律的研究方法和实验设计 .风洞模拟实验的突出特点是 ,可以在基本剔除干扰因素影响的情况下模拟和测量不同环境条件下火头前方气流的温度场和速度场 .大空间模拟实验更加接近实际火场情况 .两种模拟实验的数据采集分析系统 (包括软件 )都是针对研究特点而设计的 This paper introduces the research methods and experimental design of the law of the airflow velocity field and temperature field in front of the fire head in the field under different fire intensity, gradient and ambient wind speed.The salient feature of the wind tunnel simulation experiment is that it can basically eliminate the influence of interference factors The simulation and measurement of the temperature field and the velocity field of the airflow in front of the fire head under different environmental conditions.The large space simulation experiment is closer to the actual fire situation.The data acquisition and analysis system (including the software) of the two kinds of simulation experiments are designed for the research characteristics of
