合理的气流组织,有利于改善室内通风效果。利用CFD技术,对某设备间的四种通风方案进行了数值模拟与分析,得出了四种方案在水平和垂直方向上的温度分布规律,并以工作区平均温度作为评价指标,比较了四种方案的通风效果。研究结果表明,采用下送上排的气流组织形式,可以降低工作区平均温度1.3℃,取得更好的通风效果。其研究结果,可供相关工业建筑通风设计参考。 Reasonable airflow organization, is conducive to improving indoor ventilation. Using CFD technology, the four ventilation schemes of a certain equipment were numerically simulated and analyzed, and the temperature distribution patterns of the four schemes in horizontal and vertical directions were obtained. Taking the average temperature in the work area as the evaluation index, Ventilation effect of the program. The results show that using the air flow organized in the upper row can reduce the average working zone temperature by 1.3 ℃ and achieve better ventilation effect. The results of the study can be used as a reference for the ventilation design of related industrial buildings.
