Analysis and Optimization of Inlet and Outlet Boundary Conditions for Flow Simulations in Circle of Willis

Analysis and Optimization of Inlet and Outlet Boundary Conditions for Flow Simulations in Circle... Blood flow simulation of complex arterial networks in three‐dimensions generally involves assigning multiple inlets and outlets. This work investigates different kinds of boundary condition assigned on inlets and outlets in the Circle of Willis. These boundary conditions will be adopted in a way that a realistic velocity profile and pressure in the main brain arteries are achieved. The result of this work will be used for Fluid–structure interaction simulations. As the force applied on the artery wall depends on the blood pressure, the goal is to achieve a pressure boundary condition based on the in‐vivo flow rates in each artery.

Abstract

Blood flow simulation of complex arterial networks in three‐dimensions generally involves assigning multiple inlets and outlets. This work investigates different kinds of boundary condition assigned on inlets and outlets in the Circle of Willis. These boundary conditions will be adopted in a way that a realistic velocity profile and pressure in the main brain arteries are achieved. The result of this work will be used for Fluid–structure interaction simulations. As the force applied on the artery wall depends on the blood pressure, the goal is to achieve a pressure boundary condition based on the in‐vivo flow rates in each artery.
