“…Results indicate that acoustic cavitation and the related effects, such as the formation of microjets are the principle physical mechanisms behind the ultrasonic textile washing process. In their new study they developed a simple semi-empirical methodology for estimation of mass transfer enhancement [20].…”

“…In the absence of precise knowledge of the convection velocity resulting from transient cavitation, a semi-empirical method is used to estimate mass transfer enhancement. [ 61 ] The experimental soil removal rate during the model process is determined by precise time-controlled ultrasonic treatment of the textile, with the source of cavitation nuclei located close to the textile surface. The mass transfer in the textile during the process is found to occur in two distinct steps characterized by two different convective diffusion coeffi cients.…”

In spite of the great potential of applying high-intensity ultrasound, which enables high-temperature and high-pressure chemistry with a reactor near room temperature and ambient pressure, sonochemistry at solid surfaces is at a weak stage of understanding with regards to the development of new materials and composite nanostructures. The science towards a quantitative understanding is only now emerging. On the other hand, in many applications an ultrasonic bath is used without thinking of the mechanism. Often surfaces are exposed to ultrasound for cleaning. Since ultrasonic treatment is not an exotic process and applicable even on large scale in industrial manufacturing, controlling the process may lead to new applications making use of the specially designed surface. This review is intended to summarize recent progress in this field and to point out most promising directions of ultrasound application for the development of new materials with functional surfaces.

“…This produces bubble nucleation near the fiber loading nano N-ZnO particles onto the wool fiber surfaces [31]. Moreover, the created micro-jets with transient collapse in the near of the fibers lead to migration of nano N-ZnO particles to the fiber surfaces [32].…”
