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 ]
Molecules flow into the tube (to the left) when the pressure in the tube is low (it is sucked into the tube via X 3, coming from the orifice and the buffer). Upon entering the tube, it has the temperature T H. Later in the cycle, the same mass of gas is pushed out from the tube again when the pressure inside the tube is high.
Recuperative multi-tube coolers essentially exist of a turning rotor which is mostly driven via chain. At the ends of the rotor are stiff cases for product feed and outlet. The rotor is supported on running treads, as it is typical for rotary drums. The interior of the rotor exists of several tubes in a revolvertype (or planetary) arrangement.
The tube tapers to a small exit aperture at one or both ends. This tangential injection of gas results in a spiral or vortex motion within the tube, and two gas streams are withdrawn at opposite ends of the vortex tube; centrifugal force providing the isotopic separation. The spiral swirling flow decays downstream of the feed inlet due to ...
The free-piston Stirling cooler (FPSC) is a completely sealed heat transfer system that has only two moving parts (a piston and a displacer), and which can use helium as the working fluid. The piston is typically driven by an oscillating magnetic field that is the source of the power needed to drive the refrigeration cycle.
A Scientific Industries Inc. Vortex-Genie 2 vortex mixer in operation A vortex mixer , or vortexer , is a simple device used commonly in laboratories to mix small vials of liquid. It consists of an electric motor with the drive shaft oriented vertically and attached to a cupped rubber piece mounted slightly off-center.
