 Abstract
Mass flow amplifier, which is an aerodynamic device, makes air flow increased by ejecting small amount of compressed air with effect. In this study, the flow characteristics of a mass flow amplifier were studied with various flow conditions and geometrical configurations. In order to improve the performance of mass flow amplifier, various values of clearance, diffuser angle and the aspect ratio of induced flow inlet to outlet were considered as design parameter. Furthermore, four different pressure conditions of compressed air were also considered. Numerical study was performed using the commercial CFD code, ANSYS CFX 14.5 with shear stress transport(SST) turbulent model. The results of pressure and velocity distributions were graphically depicted with different geometrical configurations and operating conditions.
