Two series of experiments were conducted, one using a single liquid jet from a cylindrical nozzle modeled on a liquid oxygen (LOX) post, and the other using gas/liquid jets of a coaxial injector element to study flow characteristics of an injector of liquid rocket engines. Flows inside the nozzle and the coaxial injector were visualized with a high-speed video camera. From the experiments, it was found that the flow in the cylindrical nozzle was affected by cavitation generated by an inlet orifice mounted at the LOX post inlet. Discharge coefficients of coaxial injectors with a recessed LOX post were found to be quite sensitive to a variation of injection pressure drop. It was confirmed that the discharge coefficient was largely affected by the interaction between the gas flow and the liquid jet in the LOX post recess.
