Stokes flow in an elastic tube - a model for flow in collapsible tubes

摘要

This paper presents the results obtained from an improved model in which the fluid flow was described using the steady 3D Stokes equations thereby giving the first entirely self-consistent model for viscous flow in a collapsible tube. FiniteElement methods were used to discretise the fluid and solid equations and a segregated approach was used to solve the coupled problem (Heil 1996).
