The ability of a gaseous vortex to contain a foreign gas within the core was evaluated. Carbon dioxide was injected axially, from exit to entrance, into the core of a vortex created by tangential injection of air into a vortex chamber. A suction tube in the back wall of the chamber was used to obtain the mixture in the core for chemical analysis. Carbon dioxide concentration in the core was measured at varying points of injection for vortex tube diameters of 1, 1 12 and 2 inches. Tests were conducted for four different flow rates of the vortex. It was found that carbon dioxide concentration decreased rapidly with axial distance from the point of injection, and maximum concentration at a given point generally decreased with an increase in the ratio of air mass flow to vortex tube diameter.
