摘要： 利用Simtec 软件模拟巴黎圣母院火灾的温度场、烟气浓度场和风流速度场。结果表明：尖塔内部出现明显的温度分区，尖塔顶部温度较低，尖塔中部以下温度较高；火源上方温度迅速达到900 ℃，然后在900~1 000 ℃上下波动，尖塔中部温度在560~720 ℃波动，十字形屋顶温度缓慢上升；火灾烟气首先充满整个尖塔，然后逐渐扩散至整个十字形屋顶；由于烟囱效应，尖塔中部的空气流速较大，形成长约15 m 的高速区域，而塔尖和塔底部空气流速较低。

Abstract: The temperature field, smoke concentration field and wind velocity field of fire in Notre Dame fire in Paris was simulated by Simtec. The result of the simulation showed that there are obvious temperature zones inside the spire. The temperature in the spire is lower and the temperature in the middle of the spire is higher. The temperature above the fire source reached 900 ℃ quickly, and then fluctuated up and down at 900~1 000 ℃. The temperature in the middle of the spire fluctuated at 560~720 ℃ . The temperature of the cross roof rose slowly. The movement of fire smoke is to fill the whole spire at first, and then gradually spread to the whole cross roof. Due to the chimney effect, the air velocity in the middle of the spire is relatively large, forming a high speed area about 15 m long, while the air velocity at the top and bottom of the tower is lower.
