摘要
通过模拟实验方法研究了顺风条件下木材表面的火蔓延特性；连续观察和记录了木材表面的火蔓延行为，并利用温度示踪技术连续考察和分析了木材表面的火蔓延过程；分析讨论了木材在顺流条件下的火蔓延机理．同时，测量获取了不同木材表面在不同来流条件下的温度和火蔓延速率，为建立相应模型提供实验依据．
This paper is based on the results of experimental observation. A gas liquid two phase mathematical model of air cooled condenser's horizontal stratified flow type is founded. At the same time, the steady equations correlating were set up. The calculation results including the parameters of void fraction, quality, heat transfer coefficient, vapor phase velocity and liquid phase velocity have are obtained. In the end, the effect of the gas liquid separator on the improvement of the condenser's condense performance is analyzed and calculated.
