Oscillatory flow about a pair of circular cylinders is considered. The distance between the cylinders can be varied as can the angle that the undisturbed oscillatory flow makes with the line joining the cylinder centres. In common with other fluid flows dominated by oscillatory flow, a time-independent, or steady streaming, motion develops. Attention is focused on the case of high streaming Reynolds numbers and the resulting jets that erupt from the surfaces of the cylinders.
