Abstract :
New hybrid Eulerian/Lagrangian model is presented accounting for the two-way coupling between the
pulsating blood flow and the artery deformability. The Streamline-Upwind/Petrove--Galerkin (SUPG) finite
element technique is used to treat for the convective nature of the momentum equation. The deformability of
the artery walls is accounted for by treating the wall as an elastic beam under transverse unsteady distributed
load, namely the fluid pressure. The results of the present contribution compare well against the available
published data.
