Secondary instability and breakdown to turbulence in curved channel flow

Abstract

The effect of curvature on laminar channel flow is studied experimentally, with a focus on secondary instability of the counter-rotating longitudinal vortices set up by the centrifugal force. It is shown that two types of secondary instability, with distinctly different frequencies, are at hand simultaneously, and their spatial distribution and growth are determined.
