In the present work, injection of liquid kerosene into a high-pressure subsonic air crossflow was investigated experimentally. Tests were conducted at air pressures up to 2.0 MPa and at air temperatures from normal temperature to elevated temperature. Liquid kerosene was injected at room temperature through a 0.5 mm diameter plain orifice. Schlieren imaging technique was used for jet structure visualization, from which the jet penetration trajectory was determined by the image processing. For the conditions tested, a correlation of jet penetration trajectory was developed, with momentum flux ratio, Weber number and crossflow temperature ratio as independent variables. Upper surface trajectories of kerosene spray under different test conditions were compared. Experimental and analytical results showed that the penetration trajectory of liquid kerosene under higher air temperature was greater than that under normal temperature, while momentum ratios were the same.
