The vortex tube is well-matched to this application : machine shops generally already use compressed air, and a fast jet of cold air provides both cooling and removal of the " chips " produced by the tool.

In general, the evolution of vorticity can be broken into contributions from advection ( as vortex tubes move with the flow ), stretching and twisting ( as vortex tubes are pulled or twisted by the flow ) and baroclinic vorticity generation, which occurs whenever there is a density gradient along surfaces of constant pressure.

Enhancement of the centrifugal forces is achieved by dilution of Uranium Enrichment Corporation of South Africa ( UCOR ) developed and deployed the continuous Helikon vortex separation cascade for high production rate low enrichment and the substantially different semi-batch Pelsakon low production rate high enrichment cascade both using a particular vortex tube separator design, and both embodied in industrial plant.

Hence there is no radiative greenhouse effect on Venus which can be explained with any valid energy budget and corresponding Stefan-Boltzmann calculations . ( There is a totally different and valid explanation based on standard physics and supported by evidence such as in the Ranque-Hilsch vortex tube but " this is not the issue in this dispute " .)
