Study on floating phenomenon of metal disc on water surface
In this paper,the phenomenon that a metal disk with a hole in the center can float on water surface is studied theoretically and experimentally.The turbulence model and the VOF model are established,and the critical condition of floating metal disk is obtained through the force analysis of floating metal disk on the water surface.The results show that the radius difference of small hole,the density of the disc itself,the water flow rate and the size of the outlet hole are the main factors affecting the floating surface of the metal disc.According to the theoretical analy-sis,the model is established and the simulation analysis and experiments are carried out.The results show that the experimental results and the simulation results are consistent with the theoretical analysis and have certain applica-tion value.
