Abstract
The present invention relates to systems and methods for cleaning of devices, such as heat exchangers. According to the invention, controlled cavitation is created at predetermined positions within a device. The cavitation is done by mechanical waves, such as ultrasound waves, generated by transducers, wherein the waves are based on output of time-reversal wave form analysis of the device structures.
