大空间建筑顶部送风系统模型试验自模区的试验判定

Experimental estimation of self-similarity in model experiment of top supply air system in large-space buildings

以某地下大型厂房为例,把弗劳德数转化成具有相同物理意义的热量阿基米得数,对顶部送风系统模型试验所测的数据运用数理统计的方法进行适当的处理与分析,得出了模型与原型的气流流动都处于弗劳德数自模区的重要结论。

Taking an underground large-space workshop as an example, converts the Froude number into the thermal Archimedes number with similar physical meaning, by means of mathematical statistics deals with and analyses appropriately the data tested in the model experiment, and concludes that the air flowing in model and prototype is both in self-similarity of the Froude number.
