将火灾模型和烟气传感器结合起来模拟传感器对不同火灾情况的反应。将NIST的FDS模型和Duisburg-Essen大学通讯系统学院开发的烟气传感器模型结合了起来。某火灾烟气流动的模拟结果作为适合烟气传感器模型的输入数据。为了模拟烟气传感器,选择了几个必要的参数来描述烟气、传感器和房间的情况。烟气粒径的大小分布是描述烟气的一个重要参数。对影响粒径大小分布的烟气颗粒的凝结做了适当处理。联合模型的模拟结果与开敞式火灾和阴燃火灾的测量值做了比较。模拟了一个散射光感器和一个电离室。测量和模拟结果显示,传感器模拟的重质取决于所燃烧的燃料。
Combine the fire model with the flue gas sensor to simulate the sensor’s reaction to different fire conditions. Combining the NIST FDS model with the flue gas sensor model developed by the Duisburg-Essen University School of Communication Systems. The simulation results of a fire smoke flow are used as input data for a flue gas sensor model. In order to simulate the flue gas sensor, several parameters were chosen to describe the flue gas, the sensor and the room situation. The size distribution of flue gas is an important parameter to describe flue gas. The influence of particle size distribution of flue gas particle condensation has been properly handled. The results of the simulation of the joint model are compared with the measured values of open fire and smoldering fire. A scattering light sensor and an ionization chamber were simulated. Measurement and simulation results show that the weight of the sensor simulation depends on the fuel being burned.
