SWIRLING FLOWS IN CYCLONE CHAMBERS WITH NOZZLES OF SMALL FLOW SECTION

Experimental studies have been made of the hydrodynamics of cyclone chambers of varying geometry with tangential nozzles of small flow section. The character of the velocity and pressure distribution in the volume of such a chamber has been revealed. Dependences have been obtained for calculation of the tangential velocity at the periphery of a cyclone chamber and its resistance coeffi cient in a wide range of the flow sections (0.00138 ≤ α ≤ 0.024). For the fi rst time a relationship has been established between the phenomenon of the ejection of air into a cyclone chamber and the twist factor in its central region.
