计算流体力学在室内空气质量评价中的应用

选择CO2作为学生宿舍内空气质量的评价因子,一方面采用计算流体力学(CFD)数值模拟关窗工况下宿舍内CO2的浓度分布,另一方面实验测定该工况下宿舍内若干点的CO2浓度,并根据实测数据修正CFD数值模拟中的各类参数。在此基础上,进一步数值模拟通风状况下宿舍内CO2的浓度分布及流动状况,并对其室内空气质量进行评价。

The Application of CFD to IAQ Evaluation

Carbon dioxide is selected as the evaluation factor of school dormitory air quality. On the hand, Computational Fluid Dynamics (CFD) is applied to simulate the concentration distribution and flow pattern of carbon dioxide in the dormitory with the window closed. On the other hand, experimental analysis is applied to detect the concentration of carbon dioxide, and the data is used to correct the parameter of numerical simulation. On the basis of this, ventilated condition in the dormitory is simulated. The concentration distribution and flow pattern condition of carbon dioxide are acquired, and the evaluation on the dormitory air quantity is carried on.
