Abstract
SECONDARY flows are developed when a non-uniform stream passes through a bend, the plane of which contains the vorticity vector of the entry flow1. The importance of such secondary velocities in the erosion of river meanders was pointed out originally by Thompson2, and large transverse secondary velocities have been observed in the flow of air through pipe bends, at Cambridge and elsewhere3.
