Numerical Simulation of Flow Field and Separation Efficiency of Inclined Cut-in Double-inlet Cyclone
The three-dimension flow field and the separation efficiency of the inclined cut-in double-inlet cyclone were simulated numerically with Reynolds Stress Model (RSM).Numerical results show that the flow field nonsymmetry is improved in the inclined cut-in double-inlet cyclone and the swirl in the flow field was decreased greatly compared to that in the single-inlet cyclone.With the increase of inclined angle,both the tangential velocity and the axial velocity first increase and then decrease,reaching a peak at inclined 12 o angle and at inclined 10 ° angle,respectively.The pressure drop in the inclined cut-in double-inlet cyclone increases first and then decreases with the increase of inclined angle,reaching a maximum far lower than that in the single-inlet cyclone,while the change of the radial velocity is not obvious.The separation efficiency of the inclined cut-in double-inlet cyclone could be effectively improved and the optimum inclined angle is 10 °.
