Simulations and experiments on the flow field were used to study the internal flow and turbulence in a vane-guided hydrocyclone.The main factors resulting in droplet coalescence and breakup are viscous shear force related to the velocity gradient and the high shear stress and turbulent kinetic energy in the turbulence.Moreover

the positions in the hydrocyclone where droplets inclined to coalesce and break were investigated.In order to understand the relative importance of droplet coalescence and breakup in the vane-guided hydrocyclone

the separation performance as its characteristic was verified.The experiments on the separation performance also show that the structural parameters

such as the number and outlet angle of guided vanes

and operating parameters

such as the inlet velocity

split ratio

inlet concentration and operating temperature

affect the droplet coalescence and breakup in the vane-guided hydrocyclone.
