Abstract

Prediction of transient wall movement of an incompressible elastic tube using a finite volume procedure F.S. Henry & M.W. Collins Thermo-Fluids Engineering Research Centre, City University, London ECl V OHB, UK ABSTRACT The authors are currently engaged in the construction of a comprehensive model of the flow of blood in an artery. This model will solve for the motion of the fluid and the arterial wall in a coupled manner. In this paper, a solution procedure for the wall motion, based on the Finite Volume Method (FVM), is outlined. The FVM is commonly used in Computational Fluid Dynamics (CFD) codes. While the application of the FVM to solid mechanics is quite novel, the advantage of this approach is that coupled wall-fluid problems for flow in arterial vessels can be investigated using conventional CFD codes with relative ease. To illustrate the validity of the approach, the motion of an incompressible, thick-walled tube undergoing axisymmetric loading is considere
