Streamline in Cold Air Exhaust of Vortex Tube

The 22nd National Computational Fluid Dynamics Conference

This is a video clip of the physical property and transient phenomena of streamlined cold air exhaust of vortex tube.The video shows that the hot-and-cold split point is not in a fixed position. The shock will be located  inside the vortex tube. The video also provides an opportunity to make observations of buckling and flexing phenomena that radius of curvature of the streamline is not fixed.
