Abstract:
1. A method in connection with a vortex tube process, the method comprising: feeding a pressurized medium flow into a nozzle inlet, the medium flow expanding while moving forward, wherein the medium flow is twisted while entering a working tube; dividing the twisted medium flow into separate cold and hot flows; discharging the cold flow from the vortex tube via a cold flow head after going through a hole in a center of a wall limiting a first end of the working tube; discharging the hot flow from the vortex tube via a hot flow head after passing through the working tube having a flow valve at its second end; controlling parameters of thermodynamic processes in the vortex tube at least by preionization of the medium flow prior to flow into the vortex tube; and enabling adjustment of parameters of the conditions for a gaseous flow of a medium, by affecting the medium flow at least by one of precooling or the preionization prior to flow into the nozzle inlet.
