摘　　要：通过FLUENT软件模拟了CO2气体以恒定流量泄漏到受限空间的扩散过程,比较了封闭空间内和带有自然通风窗口的空间内CO2气体浓度场随时间变化差异及规律,并通过构建同等规模的实验舱完成了仿真模型的有效性验证。The FLUENT software was used to simulate the diffusion process of CO2 gas leaking into a confined space at a constant flow rate,The difference and regularity of the concentration field over time in a closed space and a space with a natural ventilation window were compared,and the validity of the simulation model was verified by constructing an experimental cabin of the same size.
