摘要
本文设计并实施了顶部开口半敞开式隧道火灾全尺寸实体试验;在实验基础上,建立了半敞开式公路隧道的物理模型和隧道火灾烟气流动的数学模型,并利用CFD场模拟方法模拟该隧道在与实验条件相同工况下的火灾现象,对数值模拟结果和全尺寸实体试验的数据进行比较,发现两者规律比较吻合,验证了所建模型的合理性和适用性。
In the tunnel with roof openings, full-scale experiment of tunnel fire were designed and conducted. Based on the experiment, the physical model of tunnel with openings on roof and the mathematical model of tunnel fire were presented in the paper. The tunnel fire under the same conditions as experiment was simulated using the CFD software. It was found that simulation results supported the findings of the experiment and the rationality and applicability of the presented model were validated.
