摘要: The fluid flow and oil-water separation were simulated using a Reynolds stress transport
equationmodel of turbulence in water flow and a stochastic model of oil droplet motion.
Simulation results give the axialand tangential velocity components, the pressure and
turbulence intensity distribution and droplet trajectories fora hydrocyclone of F type and
a hydrocyclone proposed by the present authors. The flow field predictions are
inqualitative agreement with the LDV measurements. The results show that the proposed
hydrocyclone has betterperformance than the hydrocyclone of F type due to creating stronger
centrifugal force and lower axial velocity.
