Book excerpt: All fluid flow problems in the human body involve interaction with the vessel wall. This volume presents a number of studies where primarily mathematical modelling has been applied to a variety of medical wall-fluid interaction problems. The medical applications discussed are highly varied, while some key clinical areas are also addressed. Unusually, a number of important medical challenges involving fluid flow are considered in combination with the relevant solid mechanics. The complexity of addressing combined fluid flow and solid behaviour is viewed positively by the book’s distinguished contributors. For the researcher it offers new scope for developing and demonstrating a mastery of the scientific principles involved.
