Acouctic emission-based feedback system for optimization of liquid processing in rotor devices
I.I. RASTEGAEVA, I.A. RASTEGAEV, A.A. VIKARCHUK, D.L. MERSON, M.N. SELEZNEV, A.YU. VINOGRADOV

The automated liquid processing solution is proposed for monitoring and control over liquid processing in rotor devices with feedback provided by acoustic emission from internal hydrodynamic processes. Two frequency bands are considered: audio-range (sound metering) and ultrasound (acoustic emission technique (AE)). Acoustic features are revealed and the stability of the AE technique with regard to external noise is demonstrated. The influence of the variation in operation conditions (rotor speed, temperature, liquid velocity, etc.) on AE parameters is revealed. Based on the obtained results, the schematics and the algorithm of the control system is suggested together with methods of automatic tuning, conditions for liquid processing in rotor devices.
Keywords: control systems with feedback, rotor devices, liquid processing, mixing of liquids, sound metering, acoustic emission.
