Interpreting the influence of liquid temperature on cavitation collapse intensity through bubble dynamic analysis

Simple Exfoliation of Bulk Gallium Selenide to Single/Few Layers by a Temperature‐Adjustment Bath‐Ultrasonic Treatment

“…When the energy reaches a certain threshold, the cavitation bubbles will collapse sharply, [35] causing a titanic impact on the edge of the layered material to complete the exfoliation. According to previous reports, [36,37] within a certain temperature range, the strength of cavitation failure increases with the increase of liquid temperature, while at a higher temperature, cavitation bubbles will expand to a larger size and have more potential energy, resulting in a better exfoliation effect. Interestingly, once the temperature of the exfoliation process exceeds the appropriate range, other changes would occur in the morphology of the nanosheets of GaSe.…”

An inverse method to fast-track the calculation of phase diagrams for sonoluminescing bubbles

“…in the high-temperature liquid where the saturation vapor pressure is high. More importantly, as the bubble expands during the rarefaction phase of the acoustic driving, a large number of water molecules would enter the bubble through evaporation and their proportion may overtake the argon fraction [12] , [16] . Therefore, we included it in the simulation and stressed that the pressure terms appearing in Eq.…”

“…The model is based on Toegel & Lohse [8] , Toegel et al [20] , Yasui [11] , and our previous study [16] . However, several modifications were made to improve the computation efficiency while preserving the robustness of the original models.…”

“…Correspondingly, D 12 is their binary diffusion constant and is determined from the kinetic theory of gases [22] . For other details of the model, the readers are referred to the aforementioned publications [8] , [11] , [16] , [20] .…”

Numerical modelling of acoustic cavitation threshold in water with non-condensable bubble nuclei

“…They showed that excess water vapor is trapped in the collapsing bubble and significantly reduces the bubble peak temperature. Recently, Peng et al [25] conducted a similar analysis for acoustic cavitation of vapor and argon mixture bubbles with initial radii of 1.5 and 4.5 and obtained the optimum liquid temperature that maximizes the bubble collapse intensity, depending on the acoustic frequency and amplitude. Dehane et al [26] , [27] , [28] , [29] also performed a numerical analysis for acoustic cavitation of ambient (or initial) bubbles with radii of 0.5–14 , including the effects of heat and mass transfer and chemical reaction.…”
