The disintegration characteristics of a liquid jet in crossflow were experimentally investigated by using shadowgraphy technique coupled with a high-speed camera and a continuous laser light. Four types of nozzles were tested with the ratio(q) of the crossflow velocity and the liquid volume flowrate, liquid viscosity in terms of breakup mode, spray trajectory, breakup points. As the viscosity of liquid increased, the penetration height and distance increased, but atomization performance became worse. The circular-shaped and the film-shaped nozzles showed the highest and the lowest jet trajectory height, respectively. The q value had a great impact on the jet trajectory height, and viscosity of injected liquid showed a minor effect.
