Abstract

Micro-cavitation processes through ultrasonic transducers are an unconventional way to extract essential oil rapidly. This paper numerically studies the interaction between the fluid and the heat flow from a constructal perspective. The ultrasound source is the pressure the piezoelectric transducer gives, which sources the flow–heat transfer interaction in the working pot. The three flows (the US, the working fluid flow, and the heat produced) interact and morph in response to the mechanical stress created by its source, a sonotrode.
