Refractive Index Matching

The three dimensional three component (3D3C) flow field inside hydrocyclone was investigated using Volumetric 3-component Velocimetry (V3V). To improve the spatial resolution of the measurement, a refractive index matching method is used in the experiment. The three components of the velocity in the hydrocyclonic flow is measured, and the measurement produced huge amount of data, which enabled detailed analysis of the hydrocyclonic flow field. The tangential and axial is quasi-symmetric while the radial velocity is non-axisymmetric. The radial velocity is one order smaller in value than the other two component. Results show V3V with index matching is a robust method to the measurement of hydrocyclone flow field.
