Title: Cavitation near the oscillating piezoelectric plate in water,
Abstract: It is known that gas bubbles on the surface bounding a fluid flow can change
the coefficient of friction and affect the parameters of the boundary layer. In
this paper, we propose a method that allows us to create, in the near-wall
region, a thin layer of liquid filled with bubbles. It will be shown that if
there is an oscillating piezoelectric plate on the surface bounding a liquid,
then, under certain conditions, cavitation develops in the boundary layer. The
relationship between the parameters of cavitation and the characteristics of
the piezoelectric plate oscillations is obtained. Possible applications are
discussed.
