住宅房间通风气流模型试验相似理论研究

Similarity theory analysis to residential ventilation model experiment

根据相似理论的基本原理,从流体动力学相似和传热相似两方面导出了住宅房间通风气流模型试验的相似准则以及相似比例尺之间的关系,为搭建试验台打下理论基础,更好地模拟真实房间的气流流动情况。

According to the basic principles of similarity theory, the similarity criteria and relationship among similarity scales for residential ventilation are exported from two aspects： similarity between hydrokinetics and similarity between diathermancy, which is a useful theoretical foundation for setting up test-bed, imitate the movement of the air flow in the real room better.
