摘要(Abstract):

结合Scheper,Lewins和Bejan的理论模型 ,对涡流管类比逆流换热器模型进行了深入地分析 ,得出了冷流分量对温度分离效应的函数关系式 ,为了解涡流管机理和实验中强化涡流管温度分离效应提供了理论依据
Based on the models of Scheper, Lewins and Bejan, a new model was established to understand the mechanism of the temperature separation effect with the cold mass flow fraction in a vortex tube by analogizing it as a heat exchanger. The results show the model can express the correlation of cold mass flow fraction to the temperature separation effect accurately.
