More complete models exist, as many authors have studied the behaviour of cyclone separators.A major limitation of any fluid mechanics model for cyclone separators is the inability to predict the agglomeration of fine particles with larger particles, which has a great impact on cyclone collection efficiency.

More complete models exist, as many authors have studied the behaviour of cyclone separators.A major limitation of any fluid mechanics model for cyclone separators is the inability to predict the agglomeration of fine particles with larger particles, which has a great impact on cyclone collection efficiency.James Dyson has become a billionaire from developing and marketing bagless vacuum cleaners based on cyclonic separation of dust, initially inspired by seeing a sawdust separator at a sawmill.

As the cyclone is essentially a two phase particle-fluid system, fluid mechanics and particle transport equations can be used to describe the behaviour of a cyclone.Similar separators are used in the oil refining industry (e.g.for Fluid catalytic cracking) to achieve fast separation of the catalyst particles from the reacting gases and vapors.In non-equilibrium conditions when radial acceleration is not zero, the general equation from above must be solved.Rearranging terms we obtain , possibly based upon the injection angle, and a cutoff radius, a characteristic particle filtering radius can be estimated, above which particles will be removed from the gas stream. For example, the geometry of the separator is not considered, the particles are assumed to achieve a steady state and the effect of the vortex inversion at the base of the cyclone is also ignored, all behaviours which are unlikely to be achieved in a cyclone at real operating conditions.The cyclone geometry, together with volumetric flow rate, defines the cut point of the cyclone.This is the size of particle that will be removed from the stream with a 50% efficiency.Smaller cyclones are used to separate airborne particles for analysis.Some are small enough to be worn clipped to clothing, and are used to separate respirable particles for later analysis.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.
