LIQUID-AND-GAS EJECTOR Russian patent published in 1999 - IPC

FIELD: forming vacuum. SUBSTANCE: distance between nozzle exit section and inlet section of mixing chamber is found from the following expression: where L is distance between nozzle exit section and inlet section of mixing chamber, mm; k is coefficient equal to 0.001 to 0.3; α is ration of minimum flow section of nozzle to area of minimum flow section of mixing chamber; G is flow rate of liquid medium through nozzle, g/s; (g/c)μ is flow parameter on nozzle, (g/s,sq.mm) ranging from 0.5 to 1.1. EFFECT: enhanced efficiency of ejector. 1 dwg
