Upper layer thickness and temperature rise in a fire in two rooms connected through a side vent were numerically investigated. Side vents of SV-1 and SV-2 were installed between two rooms (R-1 and R-2) and between R-2 and the outside, respectively. Situations in which fires occurred in R-1 and R-2, referred to as R-1-F and R-2-F, respectively, were tested. Effects of heat release rate (HRR), SV-1 width (), SV-2 width (), and room boundary wall material () on the upper layer thickness and temperature rise in the fire and adjacent rooms were examined using the velocity profile and mass flow rate of vent flow. and had the greatest impact on the upper layer thickness in R-1 of R-1-F and in the other rooms, respectively, whereas the effect of was the smallest. HRR and had the greatest and smallest impacts, respectively, on the upper layer temperature rise. Bias factors and model's relative standard deviations of upper layer thickness, upper layer temperature rise, and vent flow velocity were evaluated. Based on the numerical simulation data and bias factor, correlations for predicting the upper layer temperature rises in the fire and adjacent rooms of R-1-F and R-2-F were proposed.

通过侧通风口相连的两个房间火灾时上层厚度和温升的数值研究

对通过侧通风口连接的两个房间发生火灾时的上层厚度和温升进行了数值研究。 SV-1 和 SV-2 的侧通风口分别安装在两个房间（R-1 和 R-2）之间以及 R-2 与室外之间。对 R-1 和 R-2（分别称为 R-1-F 和 R-2-F）发生火灾的情况进行了测试。使用速度剖面检查热释放率 (HRR)、SV-1 宽度 ()、SV-2 宽度 () 和房间边界墙材料 () 对火灾和相邻房间上层厚度和温升的影响和排气流量的质量流量。和 对R-1、R-1-F和其他房间上层厚度的影响最大，而 的影响最小。 HRR 和 HRR 对上层温升的影响分别最大和最小。评估了上层厚度、上层温升和排气流速的偏差因子和模型的相对标准偏差。基于数值模拟数据和偏差因子，提出了预测R-1-F和R-2-F火灾及邻近房间上层温升的相关性。
