I am doing research on flows in a sharp corner. The corner is unbounded away from the vertex. A disturbance from far field generates a symmetric flow in the corner (symmetric along the mid-axis of corner). Is there any particular far-field property/boundary conditions of the stream function? eg: In a polar coordinate system, with vertex of the corner as origin, is there any known function that describes the stream function or its derivatives (function of theta) at some large r=R from the vertex for a random disturbance at infinity?

Thanks in advance!
