This study aims to determine the pressure characteristics of the convergent-divergent injector with varying suction diameter. Characteristic determination is done by simulation using ANSYS FLUENT software. The convergent-divergent injector has 28 mm suction chamber diameter dimensions, 14 mm nozzle input diameter, 58 mm suction chamber length, 5 mm nozzle output diameter, 130 mm mixing chamber length, 95 mm throat length, 130 mm diffuser length, and the output side diameter 40 mm injector. The primary nozzle used has a length dimension of 100 mm, an input diameter of 14 mm, and an output diameter of 5 mm. The injector suction was varied with successive diameters of 10 mm, 15 mm, and 20 mm. The results showed that the injector suction diameter has a significant effect on the vapor pressure characteristics of the convergent-divergent injector.
