建筑物火灾室温预测网络模型的算例验证与实验

论述了室温网络模型及其隐式差分方程,对烟流性状预测软件中的室温预测部分进行了算例验证与实验研究,结果表明:算例计算结果与日本同类软件的计算结果基本相同,软件的计算结果与实验结果吻合得很好,完全符合火灾时室温的发展与变化规律.

Example Verification and Experimental Study of Network Model for Room Temperature Prediction during the Fire in Buildings

The network model for room temperature and its implicit differential equation are discussed in this paper. The example verification and experimental study were carried out for the prediction of the room temperature in the software of predicting the properties of smoke flow. The results show that the results of example computation are similar to those obtained by similar software in Japan. The results of computation by the software tally with the experimental ones and accord with the law of development and change of room temperature during the fire.
