Fluid-active structure interaction: Arterial flow. (Interaction fluide-structure active: Écoulement artériel.) (French. Abridged English version) Zbl 0873.76099

Summary: A fluid-active structure interaction problem applied to the case of blood flow in arteries is solved using the finite volume method for the fluid and the membrane theory for the solid. The active properties of the arterial wall (autoregulation mechanisms) are taken into account and are represented in the model by a modification of the rheological parameters of the wall. The results show that: (i) we must consider the autoregulation law in the mathematical model of arterial flows, and (ii) the kinematics of the arterial wall seems to be more sensitive to the autoregulation mechanism based on shear stress than to the mechanism based on pressure.
