Acoustic streaming in a channel bifurcated by an elastic membrane. - 58 p.

Thesis (M.S.)--University of Massachusetts Lowell, 2013.

Acoustic streaming induced in a narrow channel partitioned along its long axis by an elastic membrane is examined. Adjusting the impedance of the membrane allows one to control the spatial characteristics of the time-averaged fluid motion. In addition to the time-averaged flow induced by the oscillatory motion of the elastic membrane, the effective surface stress at the boundary is considered. To this end, the solution to the velocity field is evaluated in terms of elemental Stoklets. At high oscillatory Reynolds numbers, regularization procedures to deal with singularities that occur in the formulation are addressed. For the time dependent flow, a Stokeslet formulation of the linearized equation of motion is used to express the particle velocity of fluid that results from the application of a point force. This force is the result of the gradient of the Reynolds stress. Results for oscillatory and time-averaged fluid motion are presented. An expression relating force and velocity is used to find the force generated by a given velocity boundary condition.
