Abstract
We describe a theory of blood hammer in a long and stiffened artery affected by the presence of plaque. Based on the model of a viscous fluid in laminar flow, we derive explicit expressions of oscillatory pressure and wall shear stress when part of the blood vessel is lined with thin plaque. The asymptotic method of multiple-scale expansions is utilized to obtain information on wave reflection and frictional damping analytically. The effects of plaque thickness and length on blood pressure and wall shear stress are studied.
