Theoretical study of the flowfield inside a hydrocyclone for higher Reynolds numbers

The axi-symmetric turbulent boundary layers formed on the conical surface and under the roof of different hydrocyclones have been studied for higher Reynolds numbers. Calculating the total flux through the boundary layers it has been found that the mathematical model for the flowfield, presented in a previous paper [2] for the 1/7th power law velocity distribution, holds even for higher Reynolds numbers and for different cyclones with vortex finder diameters greater than that of apex opening. Theoretical results agree well with previous experimental findings.A part of this work was performed in the Mining Engineering Department of Delft University of Technology, The Netherlands.
