In the present study, the numerical simulation has been performed to investigate the performance of the gas-liquid ejector. The aim of this research is to analyze the influence of variable motive pressure and the suction chamber size on the performance of ejector. The commercial CFD software, ANSYS CFX with the proper modeling was applied for analyzing the internal flow. This simulation was conducted in the variation of motive pressure and suction chamber size. The air and water were selected as the operation gas and liquid. In the results, the mass flow rate of air and water increase when the motive pressure increases. The gas-liquid mass flow rates ratio almost constant regardless of the increase of the motive pressure. The more water was inhaled by increasing the suction chamber size. The results is showing that the mass flow rates of air and water are influenced by the motive pressure and the suction chamber size.
