| Abstract: |
| The separation of gas-liquid two-phase flow in the cyclone separator is a compound process of centrifugal separation ，coalescence and breakup of droplets. The mechanism of droplets coalescence and breakup were discussed. The effects of liquid viscosity and turbulence intensity on droplets coalescence，breakup and separation performance were proved by experiments. The experimental results show that the liquid viscosity has much effect on droplets breakup in vortex field, and the separation efficiency increases with the liquid viscosity increasing. The turbulence intensity is the main force which breaks up the droplets. When the flow rate is up to some extent, the high turbulence intensity breaks up the droplets, then the separation efficiency will decrease sharply. While the coalescence and breakup of droplets has little effect on pressure fall in cyclone separator. |
