Simulation and Analysis of 75mm Gas-liquid Cyclone Flow Field

摘要

The inside flow field of a gas-liquid cyclone separator with a diameter of 75 mm was simulated with the computational fluid dynamics (CFD). Results showed that a variation of inlet flow rate significantly changes the inside flow field structure and affects separation efficiency. The axial velocity of sections at four different positions was studied. All absolute values of the axial velocity increased with increased inlet flow rate. The regional line diagram of axial velocity shows that the increased inlet flow rate significantly increases the axial velocity area in the upward direction and decreases the same in the downward direction.
