Effect of Viscosity on the Separation Ability of a Hydrocyclone
On bases of numerical simulation and theoretical analysis,two cases of media,water and slurry (a kind of pseudoplastic power-law fluids),were used in the same hydrocyclone under the same operating condition.The Compare results shown that the effect of the medium viscosity on the radial-velocity profile was slight; on the other hand,the effect of the media viscosity on the tangential-velocity profiles was great.The increase of the media viscosity produced not only the increase of the viscous resistance but also the steep reducing of the tangential-velocity profiles peak value,which means that the inward viscous force loading upon the particles were enforced,on the other hand,the outward centrifugal force loading on the particles reduced greatly.The increase of the media viscosity leaded to the great decrease of the separation ability of a hydrocyclone.
