为给地铁侧站台气流组织设计提供参考，评价气流组织设计蓝图，构建典型侧站台三维模型，得到合适的送风温差，优化地铁侧站台空调系统设计。物理模型是标准的 k e 湍流模型。根据实际热负荷和湿负荷确定了数值模拟的边界条件。利用CFD（计算流体动力学）对地铁侧站台的气流进行了模拟。结果表明，模拟温度场与实测温度场一致。这表明CFD能够利用标准ke模型对地铁侧站台的温度场进行准确的模拟和预测，进而为地铁侧站台空调系统的设计提供参考。
To provide a reference for the air distribution design of a subway side platform and appraise the blue print of an air distribution design, a three dimensional model for typical side platforms was constructed to got an appropriate supply air temperature difference to optimize the design of an air conditioning system of a subway side platform. The physical model is the standard k e turbulence model. Based on actual heat load and wet load the boundary conditions for the numerical simulation were determined. The air flow of a subway side platform was simulated with CFD (computational fluid dynamics). The result shows that the simulated temperature field is the same as the tested temperature field. This indicates that CFD can simulate and forecast the temperature field of a subway side platform accurately with the standard k e model, and then provide a reference for the design of the air conditioning system of subway side platforms.
