The
degradation of hydraulic jet pump performance when the suction fluid is
a gas-liquid mixtures is not well understood. An experimental study was
conducted using a two-phase suction fluid comprising air at flow rates
from 0 to 185 Mscf/D (0-61 1/s@ ST}l) and water from 40 to 860 bbl/D
(0.074-1.6 1/s). Power fluid was water supplied at a stock jet pump.
Two-phase suction pressure ranged from 100 to 1400 psig (0.7-10 MPa),
discharge pressure from 800 to 2000 psig (6-14 MPa), and power fluid
pressure from 2000 to 3000 psig (14-21 MPa). Four nozzle to throat area
ratios were used: 0.2331 , 0.2994, 0.3786 and 0.3817. Measured values of
dimensionless pressure recovery and pump efficiency are modeled using
the industry standard liquid equations. Friction loss factors for the
nozzle and throat-diffuser are statistically modeled on dimensionless
pump geometric factors and operating conditions.
