LIQUID AND-GAS EJECTOR

摘要

FIELD: evacuation technique. SUBSTANCE: area of minimum section of ejector mixing chamber is found from the following mathematical expression: where F is area is minimum section of mixing chamber (sq mm); k is coefficient (); O is volumetric flow rate of liquid medium via nozzle (cu dm/s); gamma is density of liquid medium fed to nozzle (kg/cu m); Pl is pressure of liquid medium at nozzle inlet (Pa); g is free fall acceleration (m/sq.s); magnitude of coefficient "k" ranges from 1.6 to 60 at ratio of nozzle inlet pressure to mixing chamber outlet pressure ranging from 1.4 to 25 and from 60 to 2200 at ratio of nozzle inlet pressure to mixing chamber outlet pressure ranging from 25 to 5000. EFFECT: enhanced efficiency of ejector. 1 dwg
