Summary

The aim of the subject is to present the basic physical ideas of specific features of the liquids expanding from the high pressures, for which the compressibility is non-omissible. The main emphasis is aimed at the insight into the basic differences of flows with Reynolds number overcoming by several orders those occurring with common turbulent flows. Special attention is aimed at liquid outflow when the liquid is compressed over 10%, especially at the physical phenomena inside the energy transducer (the nozzle), expansion outside the nozzle and flow development in the fluid or non-homogenous continuum including jet decay. Application of CFD method and its limitations is presented. Cavitation effects, pressure drop movement along the high pressure tubing, electric and magnetic field influence, etc. are discussed as well.
