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

FIELD: evacuation technique. SUBSTANCE: distance between exit section of each nozzle and inlet section of mixing chamber corresponding to this nozzle is found from the following mathematical expression: where L is distance between nozzle exit section and inlet section of mixing chamber (mm); k is coefficient whose magnitude ranges from 0.001 to 0.3 ((s/mm^0,25)); F_s is area of minium flow section of nozzle (sq. mm); F_k is area of minimum flow section of mixing chamber (sq.mm); P is pressure of liquid at nozzle inlet (Pa); g is free fall acceleration (m/sq. s) and γ is density of liquid fed to nozzle (kg/cu.mm). EFFECT: enhanced efficiency of ejector. 1 dwg
