Dynamic fluid-structure interaction using finite volume unstructured mesh procedures

摘要

A three-dimensional finite volume, unstructured mesh (FV-UM) method for dynamic fluid-structure interaction (DFSI) is described. Fluid structure interaction, as applied to flexible structures, has wide application in diverse areas such as flutter in aircraft, wind response of buildings, flows in elastic pipes and blood vessels. It involves the coupling of fluid flow and structural mechanics, two field that are conventionally modelled using two dissimilar methods, thus a single comprehensive computational model of both phenomena is a considerable challenge.
