Abstract
The aim of this paper is to investigate the potential use of ultrasonic waves for improving the performances of heat exchangers. In a heat exchanger, the effect of ultrasonic vibrations is important both for heat transfer intensification and for the possibility of obtaining fouling reduction: the cumulative effect determines an undeniable advantage in term of efficiency increase. After a general analysis of the topic, the results recently obtained in the two main fields of analysis, heat transfer coefficient enhancement and fouling reduction are analyzed and the perspective of the use of ultrasound for optimization of heat exchangers operation is some particular fields of application are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
