A reciprocal theorem for boundary-driven channel flows

  title={A reciprocal theorem for boundary-driven channel flows},
  author={S{\'e}bastien Michelin and Eric Lauga},
In a variety of physical situations, a bulk viscous flow is induced by a distribution of surface velocities, for example, in di↵usiophoresis (as a result of chemical gradients) and above carpets of cilia (as a result of biological activity). When such boundarydriven flows are used to pump fluids, the primary quantity of interest is the induced flow rate. In this letter, we propose a method, based on the reciprocal theorem of Stokes flows, to compute the net flow rate for arbitrary flow… CONTINUE READING
