title: Resonant acoustical pumping of a compressible viscous fluid through a planar duct or a circular tube.
abstract: Pumping of a compressible viscous fluid through a planar duct or a circular tube due to running waves on the surface of the duct or tube is studied on the basis of the Navier-Stokes equations. The flux is calculated to second order in the amplitude of the exciting surface waves. It is shown that the flux exhibits a resonance as a function of frequency, leading to a high pumping velocity near resonance.
