摘　　要：以steckler房间火试验的数据为基准,选取开口不同和火源位置不同的三个有代表性的工况,对其进行数值模拟,将模拟数据与试验数据进行对比分析,结果表明在采用合理的湍流模型-大涡模型、辐射模型-DO模型和火源模型-体积热源的情况下,FLUENT对于房间火的烟气温度及烟气流动情况具有较高的模拟精度,误差基本上在10%以内,模拟结果具有较高的可靠性,FLUENT软件可以精确预测各种工况下房间火烟气流动和温度分布的情况。Referring to the data of steckler＇s room fire test, different opening position and ignition location at three representative conditions were selected to simulate. The comparison between simulated results and experimental data was carried out. It is found that, when the turbulence model- large eddy simulation model, radiation model-DO model and combustion model- volumetric heat source are adopted, the simulation accuracy of FLUENT is high for gas temperature and gas flow and the error of simulation results is within 10%. Therefore, the simulation results are high reliability and FLUENT software could accurately predict the conditions of fire smoke flow and temperature distribution for various room situation.
