Theoretical and experimental study on the stability of the frisbee vortices

结合流体力学及流体动力学的相关内容,研究飞盘漩涡产生的原因和机理,探讨影响漩涡运动和稳定性的相关参量,进一步通过实验对其进行验证.结果表明,圆盘直径越大,漩涡越稳定;拨水速度达到特定值,漩涡越稳定;圆盘入水深度越大,漩涡越稳定;对于同一个圆盘,池水越深,漩涡越稳定;漩涡能量衰减形式为指数衰减.

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.
