Separation Performance of the Hydrocyclone

Transactions of the Japan Society of Mechanical Engineers, 1961
The motion of solid particles within a hydrocyclone is analysed by solving dynamical equations in two dimensions, and with the aid of these equations the method of calculating the fractional recovery of particles is presented. Separation data by various previous experiments are in satisfactory agreement with the theoretical curves obtained by this ...
