Abstract

The hydrocyclone separation is highly related to its flow field. The investigation of the turbulent flow characteristics helps the optimization of the hydrocyclone structure design. In this article, the turbulent flow field in a 50mm hydrocyclone was investigated with Particle Image Velocimetry. The cylinder section and part of the cone section are measured simultaneously. Both the axial and radial velocity components peak in the central area of the hydrocyclone. But for radial velocity, it varies between inward and outward from top to bottom, not exclusively inward in the cone section. The secondary vortexes exist in the transition area of inner spiral flow and outer spiral flow, where higher vorticity is located. Turbulent intensity and Reynolds shear stress is calculated from the two velocity components with time series. It has been made clear that the central area is where the turbulence is strongest. And the maximum radial turbulence intensity exists in the vicinity of vortex finder tip, while maximum axial turbulence intensity exists in the lower cone section with transition of flow. Results show the averaged velocity field is smoother and more convenient for comprehending while the instantaneous velocity field is less distorted by the averaging process.
