摘要
分析利用缩尺模型模拟火灾发展时,缩尺模型与原型应满足的相似关系,介绍参数无因次化的方法。利用FDS模拟计算缩尺模型的火灾发展并与原型的火灾模拟结果进行比较分析。结果表明,缩尺模型比例为1/20时,原型及缩尺模型火灾模拟结果中的火源功率、火源上方相应位置处的温度和能见度吻合度很高,验证了缩尺模型的可靠性,为后续实验研究提供参考。
The comparability scale model used to simulate the development of fire and its prototype should have is analyzed. The method of non-dimensionalizing the parameters is introduced. The FDS simulation results of the scale model and its proto type＇s arecompared and analyzed. Result shows that when the proportion is 1/20, the fire source power, temperature and visibility above the fire source fit well, which verifies the reliability of the scale model and provides a reference for the following experimental study.
