title = "The preliminary study of oxygen-centered kerosene-swirl coaxial injector",
abstract = "The momentum flux ratio is the key parameter in determining spray characteristics and mixing efficiency of the propellants in rocket injectors. The spray characteristics of oxygen-centered kerosene-swirl coaxial (OCKSC) injector have been experimentally investigated through cold flow tests in atmospheric pressure and high back pressure. Mainly 4 categoried conditions were investigated through the cold flow tests. The spray process was obtained from analysis of high resolution digital images, thus to achieve the spray angle. The liquid and gas discharge coefficient increased as the flow rate pressure drop increasing. The spray angle became narrow with momentum flux ratio increasing. And also the spray flow field was numerically simulated to assist the analysis on the experimental data. The hot firing tests were under investigation to receive the relations that combustion efficiencies decreased as the mixture ratio and momentum flux ratio increased were obtained by far. Different recess length will be investigated in the future.",
