    The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. The gas emerging from the hot end can reach temperatures of 200 °C (390 °F), and the gas emerging from the cold end can reach −50 °C (−60 °F). [ 1 ]

    Consequently there can be no angular momentum exchange ~ only linear velocity per Sir Isaac Newton. No skater model!! According to the Gamble theory of energy transfer in a Ranque-Hilsch Vortex Tube, the transfer of energy is by "Directed Impact-Conduction" and is collision angle sensitive in the conservation of linear momentum.

    It appeared again in a letter to John William Strutt in 1871, before it was presented to the public in Maxwell's 1872 book on thermodynamics titled Theory of Heat. [3] In his letters and books, Maxwell described the agent opening the door between the chambers as a "finite being". Being a deeply religious man, he never used the word "demon".
