Acoustic microfluidics : Capillary waves and vortex flows in the cylindrical volume of a fluid drop

• We calculate the field of radiation forces in a cylindrical fluid layer on a solid substrate formed as a result of the action on a fluid of a capillary wave propagating from the axis along a free surface. We study the structure of acoustic flows excited by the radiation forces. We discuss the action of flows on small-sized particles and the possibilities of these particles to form ordered structures. © 2015, Pleiades Publishing, Ltd.
