Аннотация
The results of experimental research on the horizontal discharge of heated gas and overheated water through nozzles with channels having a round cross-section and different cutoff angles of the outlet aperture are presented. The processes of liquids and gases discharge are visualized via photographic survey and thermal-imaging diagnostics. Comparative analysis of the main characteristics of liquid and gas jets discharged at different initial conditions and channels of different configurations is performed. It is established that there is no shift in the jet axis with respect to the outlet-aperture axis during the discharge of heated gas through nozzles with a cutoff. Different behavior is observed during the discharge of overheated water through nozzles with a cutoff. In this case the jet axis is shifted towards the cutoff direction with respect to the outlet-aperture axis, which is in the interval 15°–18° depending on the initial conditions. Practical recommendations on the use of the discovered mechanisms in engine technology (during fuel atomization by nozzles) are suggested based on the research results.
