An analytical method to find the flow generated by
the basic singularities of Stokes flow in a wedge of
arbitrary angle is presented. Specifically, we solve a
biharmonic equation for the streamfunction of the
flow generated by a point stresslet singularity and
satisfying no-slip boundary conditions on the two
walls of the wedge. The method, which is readily
adapted to any other singularity type, takes full
account of any transcendental singularities arising
at the corner of the wedge. The approach is also
applicable to problems of plane strain/stress of an
elastic solid where the biharmonic equation also
governs the Airy stress function.
