摘　　要：设计了带排液结构的涡流管的基本结构并搭建了性能研究实验平台,以空气为介质,研究长径比、排液口位置、排液间隙、可凝组分浓度对涡流管性能的影响。实验结果表明:在实验所进行的冷流率范围内,制热效应随着冷流率的增加而逐渐增大,制冷效应则存在极大值;随着长径比的增加,温度效率的极值有所增大,但是当长径比达到一定的数值后,温度效率和制冷效率增加的幅度显著减小;排液口位置的改变对于涡流管温度效率和湿气脱除率的影响不大;排液间隙的存在对涡流管的冷热分离性能有影响,间隙为1 mm时湿气脱除率最小;随着可凝组分浓度的增加,湿气脱除率逐渐增大,但增大的趋势逐渐趋于平缓。The basic structure of the vortex tube with a drainage structure was designed and the experimental platform was built. Taking the air as the medium , the influence of the length to diameter ratio, the form of nozzle flow channel, pressure ratio, and the form of hot end tube on the performance of the vortex tube were studied. The experimental results indicate that in the range of the cold flow rate during the experiment, the heating effect increases with the increase of the cold flow rate , while the cooling effect has a maximum value. The extreme value of the temperature efficiency increases with the increase of the length to diameter ratio. But when the ratio of length to diameter reaches a certain value , the increase of the temperature efficiency and the refrigeration efficiency is reduced significantly. The change of the position of the discharge port has little effect on the temperature efficiency and the removal rate of the wet gas;The existence of the liquid discharge port clearance has an effect on the cold and heat separation performance , and the removal rate of wet gas is the smallest when the clearance is 1 mm;with the increase of the concentration of condensable components, the removal rate of wet gas increases gradually , but the trend of the increase tends to be gentle.
