The relationship between fractional efficiency and particle size for a cyclone can be described using a logistic equation: efficiency = 1/(1 + (d 50/d)β. To use this equation, cyclone cut diameter, d 50, and the logistic slope parameter, β, must be known. Although cyclone cut diameter can be predicted from equations previously published, no method has been available to predict β.

A cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets ...
