GaLF theoretical model


Pumping Liquid is pumped into the injection unit and liquid passes though the throat unit.
Suction Liquid velocity is accelerated and the static pressure is decreased below atmospheric pressure.
Pressurization Gas is absorbed by the liquid at the aspirator unit, and gas-liquid multiphase flow is generated. For stable gas aspiration, the location of gas suction port was optimized.
Discharge The multiphase flow is pressurized as the flow velocity slows down at the pressurization unit. Gas is dissolved into the liquid by pressurization. Static pressure of liquid decreased to atmosphere at decompression unit. As solubility decreases, bubbles are generated as oversaturated gas.
