“…On the other hand, the generated micro jets have a denting effect on the crystal surface, and excessive power may even break the crystal. The breakage of crystals in solution can also cause secondary nucleation [50] , [51] . Similarly, Ruecroft et al [52] have reported that excessive ultrasonic power can easily induce secondary nucleation, causing secondary growth of crystals.…”

“…However, despite its advantages, the application of ultrasound also poses some challenges, including energy consumption and the risk of thermal effects. Pulsed ultrasound is a commonly used technique to address the aforementioned issues. − Figure illustrates the influence of the duty ratio on crystallization. It is observed that the yield remained essentially unchanged when the duty cycle varied from 0.2 to 1.…”

An ultrasound-assisted tube crystallization device was designed for the continuous antisolvent crystallization of acetylsalicylic acid. Both the COMSOL simulation and experimental characterization showed that the designed acoustic crystallizer exhibited high energy efficiency and excellent temperature control. The effects of ultrasonic power, ultrasonic action time, supersaturation degree, and ultrasonic excitation method on the crystallization process were investigated. Due to the intensification of fluid mixing and the introduction of cavitation bubbles as the heterogeneous nucleation sites, the crystallization was significantly enhanced. The induction time of the crystallization was shortened to several hundred milliseconds. The crystallization efficiency could be as high as 80% achieved within 0.46 s. The average particle size of the crystals ranged from 8.2 to 40.1 μm, with a span value of less than 1. Meanwhile, the pulse excitation method can further reduce energy consumption while maintaining the advantages of sonocrystallization. All of these results indicate a far better performance of the present crystallization device than conventional crystallizers, validating the effectiveness of ultrasound promotion. The results also provide insights into optimal operating conditions for ultrasonic crystallization.
