“…Test plates (18) were located inside the test chamber and were attached to the plate holders. Cavitation and hydrodynamic nozzles (14) were placed in front of the test plates. The test chamber was designed to test plates with diameters from 30 mm to 80 mm and to change the distance from the nozzle to the plate between 10 mm and 150 mm.…”

“…A special design of nozzles is used to condition the jet's shear zone to enhance cavitation and increase the erosion capacity. A detailed review of the various applications of cavitation jets in the oil and gas industry and the parameters that affect their performance can be found in [14]. Cavitation can significantly increase the jet's cleaning properties and improve existing methods of high-pressure cleaning [15][16][17] by reducing the operational pressure and flow rate.…”

Groundwater wells are widely used in the energy sector, including for drinking water supplies and as water source wells in the oil and gas industry to increase production of natural gas and petroleum. Water well clogging, which can happen to any well for various reasons, is a serious problem that can lead to increased power costs due to a higher head to the pump, a reduction in the flow rate and various drawdown issues. If rehabilitation procedures do not take place in time, this can result in permanent loss of the well, and a new well must be drilled, which is not a sustainable approach. Rehabilitation methods for water wells usually include mechanical and chemical treatments, and even though these methods are well established and have been used for many years we can still observe many abandoned wells which could be rehabilitated. In this study, sets of cavitation generators are developed and used in combination with common conic hydrodynamic nozzles. This combination reduces the pressure in the system and makes the cleaning setup much lighter and more mobile. The designed nozzles were successfully used in hydrodynamic cleaning of four water wells.

“…No entanto, os métodos de teste existentes podem não ser ideais para avaliar o desgaste de materiais aeroespaciais não metálicos (ASTM G134-17, 2017). A geometria do bocal influencia significativamente as taxas de erosão, levando à realização de experimentos com vários tipos e parâmetros de bocais (El Hassan et al, 2021;Hutli et al, 2016Hutli et al, , 2017Yamauchi et al, 1995). No entanto, algumas limitações do equipamento impedem o cumprimento integral das normas de ensaio (tais como ASTM G134), necessitando de melhorias nos ajustes de impasse e utilização de pressão (ASTM G134-17, 2017;Hutli et al, 2016Hutli et al, , 2017Yamauchi et al, 1995).…”

This study is dedicated to the examination of cavitation-induced erosion, a critical factor in optimizing the efficiency of hydraulic systems, including hydropower plants and pumping systems. To accomplish this, we conducted a sensitivity analysis utilizing a cavitation jet apparatus (CJA) and an experimental configuration that featured a vertical cylindrical test tank, a submerged nozzle, and an aluminum sample (specifically, alloy 6351 T6). The study maintained a consistent standoff distance of 5 cm and an orifice diameter of 2 × 10-3 m. Two distinct nozzle geometries were tested to assess their influence on cavitation erosion. The outcomes revealed that the 20° conical sharped-edges nozzle resulted in the highest erosion rates, while the commercial nozzle (MEG 2510) caused comparatively less erosion. By standardizing the test duration to 1200 seconds and using a cavitation index of 0.14, the researchers avoided overlapping pits. In summary, the CJA, with these adjustments, demonstrated its effectiveness as a tool for evaluating the resistance of solid surfaces to cavitation.

“…The unsteady nature of cavitating flows (including the phenomena relevant to the cavitation cloud break-off at the macro-scale as well as bubble collapse at the micro-scale) generates pressure waves that travel throughout the domain [22,23]. These propagating waves will interact with the domain boundaries in different ways (varying from 100% reflection to 100% transmission) depending on the experimental set up.…”

This paper provides new physical insight into the coupling between flow dynamics and cavitation bubble cloud behaviour at conditions relevant to both cavitation inception and the more complex phenomenon of flow “choking” using a multiphase compressible framework. Understanding the cavitation bubble cloud process and the parameters that determine its break-off frequency is important for control of phenomena such as structure vibration and erosion. Initially, the role of the pressure waves in the flow development is investigated. We highlight the differences between “physical” and “artificial” numerical waves by comparing cases with different boundary and differencing schemes. We analyse in detail the prediction of the coupling of flow and cavitation dynamics in a micro-channel 20 m high containing Diesel at pressure differences 7 MPa and 8.5 MPa, corresponding to cavitation inception and "choking" conditions respectively. The results have a very good agreement with experimental data and demonstrate that pressure wave dynamics, rather than the “re-entrant jet dynamics” suggested by previous studies, determine the characteristics of the bubble cloud dynamics under “choking” conditions.
