摘要
主要从计算方法、数学模型、流动特性和性能影响因素等方面对当前国内外空气幕进行分析,并论述空气幕在冷库中的应用研究,通过对空气幕研究成果的分析,得出CFD数值模型在预测空气幕效率上更有优势、向外调整喷射角度可以提高空气幕的封闭性等结论,提出下一步研究冷库门空气幕的方向。
The current status of air curtain were introduced. The sew eral related research topics were analyzed including calculation meth- ods, mathematical models, flow characteristics, factors influencing performance of air curtain and the application research of air curtains used in the cold storage were also described. Some conclusions of current researches on air curtains were obtained such as CFD had an advantage in predicting air curtain, nozzle angle adjustment could im- prove the sealing capability of air curtain. Lastly, the further research directions of air curtain used in the cold storage were presented.
