Summary: Approaches the definition and parameters of the model cavitation technology environment. Found that the technological environment, subdued cavitation processing, is a visco-elastic-plastic body and can be described by the model Binhama-Shvedova. Implemented is the idea to review the contact zone of interaction of the system "cavitation device – technological environment" by
determining the balance of power system pressure and stress, surrounded by bubbles emerging in consideration of the fluid model as a system with distributed parameters. As the research is subject to various technological environments the cavitation is shown as viscous and plastic properties, considered taking into account the energy dissipation in cavitating environments, including the contact area on the laws change frequency independent and frequency dependent damping. This approach made it possible to reveal the physical nature of the interaction, receive analytical dependences to establish the basic parameters, including contact pressure
and impedance in the contact area «cavitation machine systems – technological environment». Research results select the input impedance compensator length λ/4 for maximum transfer conditions under which the impedance compensator system and coordination. When placing the device between the border and the environment auxiliary layer of material with the acoustic impedance ensured equality acoustic impedance device and transmission line equivalent. Then, a reflection of both boundary layer additionally installed waves are equal in amplitude, thus ensuring maximum transfer of energy to the flow of the process.
