采用第一类边界条件数值模拟具有开口的大空间建筑室内速度场与温度场

Airflow and temperature fields in a large space with openings by CFD using the first kind boundary condition

本文以上海国际体操中心为研究对象,数值模拟夏季空调工况下室内速度场与温度场。采用对流辐射耦合热平衡方法,考虑平面辐射热源修正Gebhart吸收系数,以求得的各壁面温度作为数值模拟第一类温度边界条件。计算用软件为PHOENICS。数值模拟结果与现场实测结果基本吻合。

This paper simulates numerically the airflow and temperature fields in Shanghai international Gymnastics Center at a summer day.The wall temperature distribution as the CFD boundary condition is calculated by the way of the coupled convective and radiative heat transportation, in which Gebhart coeffcient is revised for the plane radiation source. The software for the simulation is PHOENICS.The result shows a good agreement between the simulated and the measured on the site.
