The aim of this study was to experimentally investigate the characteristics of entrainment and flow in a submerged horizontal two-phase jet using central driven air-water ejector. The streamwise velocity was measured by a propeller velocity meter, and the pressures of ejector were measured with a 5-channel digital pressure indicator. The air volume fraction was calculated by dividing the suction air flow rate by the air-water mixture flow rate. As the primary flow rate increases the entrainment ratio increases slightly. The discharge coefficient for characterizing the frictional losses in the ejector nozzle was about 0.62. It was found that the horizontal mixed jet behaved like a horizontal momentum jet or a buoyancy jet with the downstream distance or the primary flow rate.
