The contaminants are cleared from the gas before they are released into the environment by venturi scrubbers that are easy to use and effective gas cleaning equipment. Venturi scrubbers use liquids to remove contaminants from the gaseous medium. In the present study, single and double-phase flows in both circular and square cross-sectional wetted venturi scrubbers are investigated by employing the computational fluid dynamics method. Air is sent to the venturi while water is injected from four circular circumferentially located nozzles. Simulations are performed for various water flow rates and air inlet velocities employing the Euler-Lagrangian-based Discrete Phase Model (DPM). The hydrodynamic performances of both types of scrubbers are compared to each other for various water flow rates, air inlet velocities and the liquid-to-gas (L/G) ratios. For the single-phase flow, it is seen that at the same air inlet velocity, the circular scrubber experiences a greater pressure reduction. For the double-phase flow, the pressure drop increases almost linearly with gas inlet velocity and water mass flow rate. As the liquid/gas (L/G) ratio increases, the pressure drop becomes significantly larger. The square cross-sectional scrubber yields the maximum collecting efficiency, approaching 96%, whereas the predicted effectiveness of the circular one is 58% at the lowest mass flow rate. It is also discovered that increasing the water flow rate and the inlet gas velocity decreases the co
