In this paper we apply a BiGlobal stability analysis technique to measure the stability of two‐dimensional constricted channel flows to three‐dimensional perturbations. Critical Reynolds numbers and spanwise perturbation wavelengths are presented for three instabilities of steady flow in constricted channels. Copyright © 2004 John Wiley & Sons, Ltd.
