Abstract: The structure of flow field and the total pressure loss in an atomizing channel injector is investigated experimentally. The results show that the total pressure loss is increased with the increase of width of channel, flow velocity and the distance from channel to fuel rod. The results also show that the difference of total pressure loss between an atomizing channel injector and a single cylinder rod is rather small under an operating condition of afterburner.This investigation is only a part of experimental program of atomizing channel injector.
