Engineering, Environmental Science. 2006. 116. Two-phase flow patterns in a mini-hydrocyclone with different insertion depths of the vortex finder were measured by a phase Doppler particle analyzer. The distributions of velocity, concentration, root-mean-square velocity, and average diameter of particles were evaluated.
The inlet oil volume fraction had little effect on the hydrocyclone flow velocity. With an increase in the inlet flow rate or oil phase volume fraction, the probability of oil droplet breaking increases, and emulsification occurs. 0.5 m/s is a better flow rate, under that, the oil volume fraction at the oil phase outlet can reach 45 %, and the ...
This paper presents a numerical study of the gas-powder-liquid flow in a standard hydrocyclone. In the approach, the turbulent fluid flow is described by the Reynolds stress model, the interface between the liquid and air core is modeled using the volume of fluid multiphase model, and the results of fluid flow are used in the simulation …
