Abstract:
Based on the study on the relevant contents of fluid mechanics and hydrodynamics, the causes and mechanisms of the frisbee vortex has been discussed. The relevant parameters that affect the vortex motion and stability can be determined by theoretical and experimental analysis. The results show that the larger the diameter of the disk, the more stable the vortices. The water speed reaches a certain value, and the vortex is more stable. The greater the depth of the disk into the water is, the more stable the vortices are. For the same disc, the deeper the water is, the more stable the vortices are. The energy attenuation form of vortices presents exponential decline.
