This work focuses on improving ejector performance in variable conditions by developing a radial flow geometry (VGRE). The research objective was to demonstrate the of improved VGRE, which can operate more effectively under changing operating compared fixed design. VGRE developed and experimentally tested enable adjustment nozzle throat areas suit different various applications. Radial ejectors have smaller size than axial ejectors, is significant advantage some Results showed that achieved higher entrainment ratio critical compression design optimal obtained with duct separations 0.5 mm 3.0 mm, respectively. results also indicated wall static pressure region similar observed conventional an average improvement 107% 76% relative previous studies air ejectors. findings suggest concept could be applied wide range applications future.
