“…Also, it has low die-electric losses, so it is most preferable for ultrasonic cleaning application. 230 V power has been applied for transducer operating (Virot et al, 2010;Zhong, 2015;Rokad and Pandya, 2021).…”

“…The erosion can be affected by a number of factors including impact angle, particle flow, particle size and shape. It is also affected by fluid properties, flow condition and material comprising the impact surface (Tangsopa and Thongsri, 2020;Rokad and Pandya, 2021).…”

The ability of ultrasound to produce highly controlled erosion phenomenon was investigated and various erosion models have been compared by considering various parameters. In cleaning industry, Vibro Cleaner (VC) has been used to remove contaminations from the surface of metal components. This process is most preferable to out of reach or critical surface of the objects. The novelty of this research is to compare various erosion models and to identify appropriate model for ultrasonic cleaning application to get meaningful results of metal removal rate. The computational model of Vibro Cleaner has been developed using pressure acoustic transient in COMSOL Multiphysics software. Acoustic and Computational Fluid Dynamics (CFD) modules have been coupled together to investigate erosion rate. In acoustic approach, acoustic pressure and sound pressure level have been studied by means of piezoelectric transducer through tank wall transience. In CFD approach, Bubbly fluid flow has been applied to get turbulence in acoustic streaming. Also, particle tracing has been coupled to understand the particle trajectories and motion of fluid flow. Erosion terms are also introduced at a surface of metal parts which need to be clean. The Erosion rate has been evaluated by using cavitation erosion phenomenon in which cavitation bubbles strike and implode over the metal surface and clean the dirt, dust, oil and other contaminations. Various Erosion models like Finnie, E/CRC, Oka and Det Norske Veritas (DNV) have been studied and results have been compared to identify appropriate erosion model towards the ultrasonic cleaning application by considering 28 kHz frequency and PZT-4 piezoelectric transducer. Comparative study leads to conclude that the Finnie erosion model have given stringent results as compare to other erosion model.

“…Compared with experimental research, the simulation has the advantages of good adjustability, intuition, and easy analysis. COMSOL is a multi-physical field simulation software based on the finite element method [8][9]. It can be used to solve the sound field in basic engineering investigations such as "ultrasonic detection", "acoustic sensor", "electromagnetic ultrasound" and "laser ultrasound".…”

This paper describes a method of simulating the ultrasonic longitudinal wave (P-wave) propagation in titanium alloy. The two-dimensional geometric model of polycrystalline titanium alloy is established using the Voronoi algorithm. Then, the model was imported into COMSOL software for grid division and parameter setting. The continuous observation of P-wave propagation was realized after adding the physical field of sound pressure and the boundary condition. Further, the first and second transmitted P-wave obtained the ultrasonic attenuation spectrum (UAS). The inverse method determines the average grain size (AGS) by fitting the UAS. It was found that the AGS D ¯ = 47.5 μm of the titanium alloy was obtained by the least square fitting method, and the relative error between the inverse value of AGS and the set value in the model approached 5%.
