摘要：
A theoretical analysis and experimental investigation of the phenomenon of impingement of a circular liquid aerosol jet on a plate have been carried out. In the case considered, the spreading of liquid on a plate is caused by inertia and air drag force; for supercritical film flow in some conditions, a hydraulic jump is formed. The circular hydraulic jump exhibits behavior quite different than commonly observed in planar jumps. A new theoretical model of the phenomena of hydraulic jump has been formulated. The experiments exhibit that the liquid layer formed by an aerosol experiences a hydraulic jump at a location more downstream than the film created by a single-phase liquid jet. Theoretical results were compared with our experimental data, and the results seem to be satisfied.
