在这项研究中，一种新的几何形状被引入冷端侧（即旋流被引入管），这是所谓的“螺旋旋流发生器”。涡流发生器的螺旋长度对涡流管性能的影响进行了研究，其他几何参数的变化值作为冷质量分数的函数，yc。最后，揭示了螺旋长度对性能的影响随L/D值的变化而变化。
In this study, a new geometry is introduced for the cold end side (i.e. where the swirl flow is introduced into the tube), which is called ‘helical swirl flow generator’. Effect of the helical length of the swirl flow generator on the performance of the vortex tube are investigated for varying values of other geometrical parameters as a function of the cold mass fraction, yc. Finally, it’s disclosed that the effect of the helical length on the performance changes critically according to the value of L/D.
