Study on a Vortex Tube : Performance Characteristics of a Steam-Operated Vortex Tube

Computational Fluid Dynamic Prediction and Physical Mechanisms Consideration of Thermal Separation and Heat Transfer Processes Inside Divergent, Straight, and Convergent Ranque–Hilsch Vortex Tubes

“…They reported that the optimum size of the cold exit is 58% of the diameter of tube, which is same as Saidi et al [53] but 8% smaller than the result of Behera et al [31]. Chang et al [55] studied the effect of a divergent vortex chamber on the performance of the VT, similar to Takahama et al [52], with variation of divergent angle of tube. They reported that the performance of the VT can be improved by using the divergent tube with a divergent angle not more than 6 ο .…”

“…Among these, Takahama [51] studied the energy separation efficiency, velocity distribution, and temperature distribution inside the tube, experimentally. Later, Takahama et al [52] studied the effects of divergent tube with a divergent angle of 1.75 ο on the performance of VT. They reported that the performance of divergent vortex chamber is better than the straight tube with the same length of tube.…”
