Abstract

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.

## Abstract We have conducted the linear stability analysis of flow in a channel with periodically grooved parts by using the spectral element method. The channel is composed of parallel plates with rectangular grooves on one side in a streamwise direction. The flow field is assumed to be two‐dimen
