The tropical cyclone is a solitary creature of the tropical oceans accompanied by violent rotating winds and torrential rain. Observational studies and diagnostic analyses leave little doubt that the energy required for driving the vortex comes from the latent heat of condensation released by tall convective clouds around the center, and that the frictionally induced inflow in the vortex …

Cyclones have been around for more than 100 years, with the first patent issued in 1886. "They have been used ever since to separate particles from an air, gas or liquid stream without the use of barrier filters across a wide range of industries," says Pedro Araujo, CEO and cofounder of Advanced Cyclone Systems S.A.

vortex finder. The primary function of the vortex finder is to control both the separation and the flow leaving the cyclone. Also, the vortex finder is sufficiently extended below the feed entrance to prevent short circuiting of material directly into the overflow. The size of the vortex finder equals 0.35 times the cyclone diameter.
