Subject aims expressed by acquired skills and competences
To interpret and generalize theoretical and practical knowledge of liquid decomposition and spraying. To analyse the conditions of origin of high-velocity liquid jet, especially the outflow of liquid from the nozzle and separation or spraying of liquid jet accordint to many factors and conditions.

Summary
The subject includes theoretical and practical knowledge of disintegration and
spaying of liquids. The physical ground and physical quantities influencing
fineness of spraying are regarded. The student is got acquainted with the
process of spraying and methods of research of liquid stream disintegration.
The process in the course of the fuel combustion and knowledge exploitation
during burning follows.
Another substantial part represents the study of the high-energy liquid jet.
