Modelling of Blood Flow in Cerebral Aneurysm Before and After Treatment

Abstract
This work presents the simulations, which are carried out to compare the effects of high blood pressure and normal blood pressure conditions. Effects of blood pressure are studied for a patient under a rest and exercise conditions. In order to cure a cerebral aneurysm, coil embolization method is more appropriate technique to rectify the aneurysm surgically. The efficacy of the coil embolization method is assessed by considering the coils to be isotropic and homogeneous porous medium. In the present study, Finite Volume Method (FVM) is implemented to discretize the 3D unsteady governing differential equations. Blood flow is considered laminar, incompressible and non-Newtonian. Carreau-Yasuda model of flow in a non-Newtonian fluid is incorporated to capture the shear thinning behavior of blood. Further, to model the porous medium, the extended Darcy model with Forchheimer and Brinkman terms is appended in the Navier-Stokes equation.
