“…During these cycles, a voltage is induced near the cavitation zone’s boundaries [ 2 , 3 , 4 ]. Cavitation is an exogenous process accompanied by discontinuities in the liquid’s state, which appear when the pressure drops under critical limits [ 5 ]. Emulsification, noise, vibrations, sonoluminescence, unpassivation, and corrosion are some of its multiple effects [ 6 , 7 ].…”

Cavitation is a physical process that produces different negative effects on the components working in conditions where it acts. One is the materials’ mass loss by corrosion–erosion when it is introduced into fluids under cavitation. This research aims at modeling the mass variation of three samples (copper, brass, and bronze) in a cavitation field produced by ultrasound in water, using four artificial intelligence methods—SVR, GRNN, GEP, and RBF networks. Utilizing six goodness-of-fit indicators (R2, MAE, RMSE, MAPE, CV, correlation between the recorded and computed values), it is shown that the best results are provided by GRNN, followed by SVR. The novelty of the approach resides in the experimental data collection and analysis.

“…Numerical calculation demonstrates that ultrasonic bubbles cause transient local high temperature and high pressure, which separately reach 10,000 Kelvin and 10,000 times atmosphere separately [39] . Both high-level temperatures and pressures bring strong temperature shock and thermal stress shock to the oxide film.…”

“…Cavitation is the process of apparition, augmentation, and collapse of the bubbles created around tiny particles in special pressure conditions in a liquid [1]. The discontinuity of the liquids' state characterizes this phenomenon when the pressure experiences a sudden local drop [2]. The cavitation that appears at the ultrasound propagation in fluids is named ultrasound cavitation [3][4][5].…”

Experiments have proved that an electrical signal appears in the ultrasonic cavitation field; its properties are influenced by the ultrasound frequency, the liquid type, and liquid characteristics such as density, viscosity, and surface tension. Still, the features of the signals are not entirely known. Therefore, we present the results on modeling the voltage collected in seawater, in ultrasound cavitation produced by a 20 kHz frequency generator, working at 80 W. Comparisons of the Box–Jenkins approaches, with artificial intelligence methods (GRNN) and hybrid (Wavelet-ARIMA and Wavelet-ANN) are provided, using different goodness of fit indicators. It is shown that the last approach gave the best model.
