“…Notably, a mere 10 °C increase in marine temperature from 25 to 35 °C leads to a significant 10.99% decrease in the microhardness of carbon steel pipes. This reduction is attributed to prolonged exposure to seawater at specific temperatures, inducing material degradation that affects the surface microhardness of the samples 45 . Moreover, the pits that formed on the sample surfaces after 28 days of seawater exposure primarily contributed to the decrease in microhardness (refer to Fig.…”

This research aims to investigate the effects of seawater parameters like salinity, pH, and temperature on the external corrosion behaviour and microhardness of offshore oil and gas carbon steel pipes. The immersion tests were performed for 28 days following ASTM G-1 standards, simulating controlled artificial marine environments with varying pH levels, salinities, and temperatures. Besides, Field emission scanning electron microscopy (FESEM) analysis is performed to study the corrosion morphology. Additionally, a Vickers microhardness tester was used for microhardness analysis. The results revealed that an increase in salinity from 33.18 to 61.10 ppt can reduce the corrosion rate by 28%. In contrast, variations in seawater pH have a significant effect on corrosion rate, with a pH decrease from 8.50 to 7 causing a 42.54% increase in corrosion rate. However, the temperature of seawater was found to be the most prominent parameter, resulting in a 76.13% increase in corrosion rate and a 10.99% reduction in the microhardness of offshore pipelines. Moreover, the response surface methodology (RSM) modelling is used to determine the optimal seawater parameters for carbon steel pipes. Furthermore, the desirability factor for these parameters was 0.999, and the experimental validation displays a good agreement with predicted model values, with around 4.65% error for corrosion rate and 1.36% error for microhardness.

“…Another experimental direction is related to the study of bubble dynamics in the stage of maximum compression. To visualize the process, the initial bubble size is chosen as being large enough (R > 1 mm) to record the size of the maximally compressed bubble R sq using the available measuring instruments [59][60][61][62][63]. If R sq < 1 µm and the bubble cannot be visualized experimentally, only pressure pulses in the liquid at a distance from the bubble or the degree of erosion damage to the surface are recorded.…”

To study the behavior of a bubble clusters in cavitation devices, a numerical study of the dynamics of bubbles in a compressible liquid was performed, taking into account interfacial heat and mass transfer. The influence of regime and system parameters on the intensity of cavitation processes is considered. Physical and chemical transformations during the cavitation treatment of liquids are caused not only by the action of shock waves and emitted pressure pulses but also by extreme thermal effects. At the stage of extreme compression of the bubble, the vapor inside the bubble and the liquid in its vicinity transform into the state of a supercritical fluid. The presented model analyzes the nature of microflows in the interbubble space and carries out a quantitative calculation of the local values of the parameters of the velocity and pressure fields.
