ABSTRACT

A BiGlobal stability analysis technique based on spectral/hp element technology is discussed, and applied to the biomedically important problem of the flow through a constricted channel. Results for both steady flows and the Floquet analysis of time periodic flow are presented. In the steady case the onset of three-dimensionality is investigated, and the effect of stenosis extent is examined. In the periodic case preliminary results concerning the initial bifurcation to asymmetry are presented.
