Study of the near field generated by a power ultrasonic transducer

Industrial processes assisted by high-power ultrasound (HPU) have become an attractive field for industries because of its sustainability (low energy consumption, non-pollutant processes). These processes are based on the proper exploitation of the non-linear effects associated to finite-amplitudewave propagation that are able to enhance mass transfer processes in food dehydration. The main objective of this work is the analysis of the acoustic field, generated by a high power ultrasonic transducer with circular radiator confined in a drying chamber, and obtained by numerical methods; as well as the parametric study of the sample location inside the chamber, in order to optimize the system efficiency.
