建筑物中的气流涉及许多不同流动元素的组合。因此，很难找到一个涵盖所有方面的充分、全面的湍流模型。因此，根据要预测的情况选择湍流模型是适当和经济的。本文讨论了不同湍流模型的使用及其在特定情况下的优势。作为一个例子，它表明，一个简单的零方程模型可以用于预测特殊情况，如低水平湍流流动。 本文还讨论了具有房间尺寸和速度水平补偿的零方程模型。采用阻尼函数扩展的k模型，改进了置换通风房间内气流的预测。阻尼函数特别考虑了湍流水平和垂直温度梯度。低雷诺数模型（LRN模型）用于改进建筑材料蒸发控制排放的预测，实例表明。最后，对室内气流的大涡模拟进行了讨论和演示。 单位:SICitation:研讨会，ASHRAE交易，1998年，第104卷，pt。1A，旧金山

The airflow in buildings involves a combination of many different flow elements. It is, therefore, difficult to find an adequate, all-round turbulence model covering all aspects. Consequently, it is appropriate and economical to choose turbulence models according to the situation that is to be predicted. This paper discusses the use of different turbulence models and their advantages in given situations. As an example, it is shown that a simple zero-equation model can be used for the prediction of special situations as flow with a low level of turbulence. A zero-equation model with compensation for room dimensions and velocity level also is discussed. A k- model expanded by damping functions is used to improve the prediction of the flow in a room ventilated by displacement ventilation. The damping functions especially take into account the turbulence level and the vertical temperature gradient. Low Reynolds number models (LRN models) are used to improve the prediction of evaporation-controlled emissions from building material, which is shown by an example. Finally, large eddy simulation (LES) of room airflow is discussed and demonstrated.Units: SI
