Abstract

The steady streaming outside the Stokes shear-wave layer, which forms on the surface of a sphere when placed close to an oscillatory point source, is considered. Particular attention is devoted to the case of high streaming Reynolds-number flow. Thin circular jets, analogous to the plane jets known to occur in two-dimensional flow, are predicted and visualized by means of a simple experiment.
