This study explores the injector jetting characteristics in aircraft engine lubrication systems using CFD simulations. The results show that varying inlet pressures significantly affect pressure loss, flow control, and ventilation efficiency. The maximum efficiency reaches 0.85, providing insights for optimizing injector design and improving lubrication system performance.
