摘要
本文给出了计算通风空用房间温度、速度分布所需的微分方程，湍流部分采用新的零方程模型．根据ＳＩＭＰＬＥ算法开发出计算通风空调房间风速、温度分布的软件ＳＴＡＣＨ－３。在利用文献中的实验资料验证该软件的基础上，对一个置换通风的例子，利用该软件预测房间内的温度场、速度场，从而指导通风空调的工程设计。
The transportation equations necessary for the calculation of temperature and ve- locity ventilated or air conditioned room are presented in the paper. The tubulence is modeled by a new zero-equation. The software, known as STACH-3, for the numerical simulation of indoor air distribution is developed with SIMPLE algorithm. With the software, the distribu- tions of temperature and velocity of a displacement ventilation room are predicted and the flow pattern are evaluated, which can favor the ventilation and air conditioning design.
