Ultrasonic wave propagation in cylindrical vessels and implications for ultrasonic reactor design [PDF]
, 2010 Reactors in which processes are enhanced by ultrasound are hampered by the lack of a theoretical framework on their design. Simulation results of ultrasonic wave propagation in a cylindrical geometry are presented in this work, which are then used to ...

Nonthermal Food Processing Technologies: A Comprehensive Review
Future Postharvest and Food, EarlyView.The graphical abstract illustrates the shift from traditional thermal food preservation methods to advanced nonthermal technologies. Traditional methods, represented by heating, often compromise the nutritional and sensory quality of foods. In contrast, nonthermal approaches such as high‐pressure processing (HPP), pulsed electric field (PEF ...
