The hydraulic performance of a modular liquid-gas ejector (LGE) unit with an air-water system is experimentally evaluated across a wide range of device scales and operating conditions. To maximize the LGE efficiency, three methods of gas entrainment rate enhancement were tested: (i) LGE flow orientation, (ii) liquid jet destabilization using a swirl in front of the nozzle, and (iii) using a high-loss nozzle producing a non-coherent liquid jet. Resulting from a broad database of experimental data, the optimal geometries for various process conditions are identified. Using the recommended geometry and liquid jet destabilization, the LGE gas entrainment rate can be multiplied compared to the performance with a coherent liquid jet. Based on the LGE hydraulic analysis, a semi-empirical model for effective LGE design is developed and experimentally validated.
