Vortex tube with ultrasonic inflow

摘要

A Laval (supersonic, convergent-divergent) nozzle is used in a vortex tube for the inflow of a gas into the rolling vessel (container). This results in a high inlet velocity of the gas in the rolling vessel, and the effect of this is a striking improvement in efficiency and thus, e.g. in the cooling effect or the separation of gases or isotopes.
