Abstract

Most fluid carrying vessels (veins, arteries, pulmonary circulation and airways, etc.) in the body are elastic and can collapse when the transmural pressure falls below a critical value. A computational model is presented of a 3-D compliant tube using a fully coupled fluid-structure interaction approach, solving full Navier-Stokes equations for the analysis of fluid flow in a tube. The wall is modeled as solid wall having finite thickness.
