· The Federal Aviation Administration (FAA) defines clear air turbulence (CAT) as "sudden severe turbulence occurring in cloudless regions that causes violent buffeting of aircraft." The FAA adds that the CAT definition is most commonly applied to higher altitude turbulence associated with wind shear, which is a change in wind direction or speed over a specific distance.

 · The classifier designs differ mainly in the mode of removing the underflow and the overflow slurries. Immersed spiral or rakes are generally used for underflow slurries and an open launder carries the overflow. Figure 13.1 is a sketch of a spiral classifier where the spiral conveyor is installed within the bowl. The spiral operates along the ...

By employing conditional averag-ing techniques, we have obtained flow statistics of a single turbulent or laminar spiral for a range of Reynolds numbers. The data demonstrate large-scale spatial variations of the flow internal to the turbulent and laminar ...

 · Centrifugal air classifiers can yield differing cut sizes by adjusting the centrifugal acceleration . The MikroCut MC classifier is a typical centrifugal classifier and can separate particles below 10 μm. However, its relatively complicated geometries and high initial cost limit its use in some industrial processes.

Forecasting severe turbulence in the free troposphere and stratosphere is challenging. The turbulence is generated by processes such as shear instabilities (Kelvin–Helmholtz instabilities), upper-level fronto-genesis, large-amplitude mountain waves and breaking of convectively generated gravity waves (Ellrod & Knapp, 1992). In particular, turbulent eddies and waves with …

 · a spiral trough when treating material coarser than 100µm will generally be inefficient in the treatment of finer material. For the recovery of heavy minerals finer than 100µm to the spiral concentrate product the flow on the spiral trough must be controlled to minimise turbulence that will entrain fine particles in the outer section of the
