Asymptotics and internal fluid dynamics

The course will focus on laminar flow through a constriction or a branching in a channel or tube, motivated by the biomedical and industrial applications. The aim is to understand and predict properties such as wall pressure and wall shear stress at flow rates which are medium to high. Steady flow is to be studied first. The asymptotic analysis addresses mild and then increasingly severe constrictions, including issues of physical scales, nonlinear effects, viscous-inviscid interaction, upstream influence and downstream influence. Comparisons with direct simulations and experiments will be described. The course will move on later to aspects of three-dimensionality, unsteadiness and /or instability.
