M. : Mechanical Engineering, 2008. 116 s. The results of the experimental study of hydrodynamics of the flow of incompressible and compressible liquids, acoustic cavitation, resonance in the working zones of the rotor apparatus and their influence on the speed of technological processes. are presented. The results of practical use of the developed structures of devices for various technological processes are presented. Designed for scientific and engineering workers dealing with non-stationary currents, cavitation and resonance in technological volumes . Can be useful for undergraduates and graduate students studying in technological specialties.
