套室内气流的三维数值模拟

借助流场计算软件PHOENICS，对单元住宅室内的气流在夏季工况条件下进行三维模拟计算。考虑了外界气温和太阳辐射等因素对室内气流的影响，得到室内气流的速度矢量和温度等参数的分布。依据供暖、通风和空气调节在夏季工况下的标准，对室内的气流温度、气流速度做出评判。通过算例验证了数值模拟的可信性。

Three-dimensional numerical simulation of the airflow in an apartment unit

The three dimensional airflow is numerically calculated with the software of computational fluid dynamics in an apartment unit with two bedrooms and one hall in the summer of 2000. The factors are taken into account such as outdoor air temperature and solar radiation. According to the summer standards of heating, ventilating and air conditioning, air temperature, air velocity and air distribution are evaluated in the apartment unit. This study lays foundations of the future research on the indoor air distribution. An example is applied to prove the validation of the numerical simulation.
