“…The course of the phenomena was confirmed during experiments carried out with the use of a specially designed tank and pump. It was confirmed that the oscillator-cavitation system, designed and manufactured on the basis of [20,22], is useful for inducing the phenomenon of ultrasonic cavitation. It was also confirmed that the PIV visualization method based on a special system of illuminating transparent objects and recording the flow through those objects by means of a fast camera are useful in the research on the cavitation phenomena [24,26].…”

The article describes the course of the ultrasonic cavitation in a hydraulic tank and the hydrodynamic cavitation in a gear pump. The course of those phenomena was confirmed in experimental tests carried out with the use of a tank and a pump made of transparent plastics. It has been proved that the oscillator-cavitation system made according to the original project is useful to induce the phenomenon of ultrasonic cavitation. It has also been shown that the PIV visualization method, consisting in a special system of illuminating transparent objects and recording the flow through those objects with a fast camera, is useful for the studying of the cavitation phenomena. A visible interaction between the ultrasonic and the hydrodynamic cavitation was observed. The induction of ultrasonic cavitation in the tank causes degassing of the oil, and the degassed oil supplying the pump reduces the hydrodynamic cavitation in its internal channels and clearances. This is an example of beneficial effects of the ultrasonic cavitation on the operation of a pump and a hydraulic system. The presented work is an example of effective co-operation between the communities of Wroclaw University of Science and Technology and Igor Sikorsky Kiyv Politechnic Institute, National Technical University of Ukraine.

“…Further, in block 2 «Formation of the technological scheme», preliminary calculations are made for the mode of energy transfer to the medium in accordance with the selected criterion. An important stage of the algorithm is blocks 3 and 5, which determine the physical and mathematical models based on the research results [7][8][9][12][13][14][15][16][17][18]. It is in blocks 4, 6, 7 that the initial data are formed to determine the numerical values of the impact parameters and the limits of their rational use.…”

“…Therefore, the determination of the parameters of acoustic treatment of technological media and energy requires the use of a computational model [10], which takes into account these changes. The key parameter of the evolution of gas and air bubbles in the acoustic field is the pressure that is formed in the contact zone of the «cavitator -medium» system [11][12][13][14]. The specified parameters and characteristics (Fig.…”

The operation process of acoustic treatment of technological media is investigated. The assessment and substantiation of methods for studying the parameters of acoustic treatment of technological media is done. The functional relationships between the acoustic parameters of the cavitation apparatus and the rheological properties of the processing technological media have been revealed. The process of staged acoustic treatment of technological media is described. A number of criteria and key parameters were determined, the use of which was carried out as an assessment in the calculation algorithm, depending on certain known initial data of the cavitator and the medium. The values of the input resistance of the compensator are determined and the condition for the maximum transfer of energy from the acoustic apparatus to the technological medium is obtained. To calculate the parameters of the «cavitator -technological medium» ultrasonic cavitation system, an algorithm and method for creating a synergistic system were developed.

“…Thus, studies using the above technique have established that for the processes of grinding [6,7], sorting [8], mixing [9], compaction [10,11], cavitation treatment [12][13][14], research of parameters, modes and reliability machines [15][16][17][18][19][20] there is a significant difference in the numerical values of the criteria of the studied class of technical systems. The main reason lies in the use of simplified models, the absence of modeling and consideration of the joint movement of the working bodies of the technical system and the processed medium or material.…”

The classification features of technological technical systems, the further development of the theory of the working process are given. The classification features are determined. Only the classification features that determine their purpose and the nature of the work they perform are considered. An assessment of the design and technological parameters of the existing technical systems of industrial engineering has been carried out. New and improved evaluation criteria have been used. Reliable assessment and analysis made it possible to formulate more reasonably methods for solving the problem. Continuously improving, the technology leaves a reflection on the directions of development of technical system designs. On the basis of this, working hypotheses were formulated, the essence of which lies in modeling the medium and technical system as a single system with their own dynamic individuality. The system «technical system -medium» is represented by a complex hybrid (mixed) dynamic system, in which the technical system is a system with discrete parameters, and the medium is with distributed parameters, and this system is reduced to the calculated one in the form of a system with discrete parameters.
