There is so much physics involved in vortices. Conservation of angular momentum and fluid dynamics are some of the main principles. When a fluid starts to rotate, it creates a difference in pressure between the inside and outside of the rotating flow. This pressure difference causes the fluid to continue rotating, forming a vortex. The swirling motion of the fluid is sustained because of the conservation of angular momentum, which means that the total amount of rotational momentum in the system

Vortex Start: Slag Treatment Process during Perforated Cutting of Thick Plates 1. Smartly choose vortex process according to the material and its thickness, sparing the need for repeated adjustments and reducing operating difficulty. 2. Remove the slag produced during perforation to the greatest extent, making sure that the cutting edges are smooth and intact. 3. Greatly improve stability of cutting follower, and prolong service life of nozzle and ceramic ring. | Bodor Laser
