Outline
This study investigates the salt spray removal characteristics of Venturi ejectors through experimental testing and computational fluid dynamics （CFD） simulations to enhance their performance. The air suction variation under different inlet water flow rates was analyzed，and a modified Venturi ejector integrated with a helical mixer was proposed to improve gas‑liquid mass transfer efficiency. Results show that the salt spray removal efficiency decreases with increasing gas‑liquid ratio （GLR），declining from 83% to 52% as GLR rises from 0.25 to 1.25. Phase stratification at high GLR reduces gas⁃liquid interfacial area by 12.5%，significantly degrading removal performance. The helical mixer‑integrated ejector maintains higher interfacial area and volumetric mass transfer coefficients under high GLR conditions. Despite a 43% reduction in air suction and a 9% increase in pressure drop after mixer integration，the mass transfer rate improves by 90%，indicating superior salt spray capture capability. These findings provide critical insights for optimizing Venturi ejector designs in desalination applications.
