A numerical analysis is carried out using ANSYS fluent tool to assess coil size and compactness value on unruptured aneurysm after coiling treatment. The study reports the effect of endovascular embolization on blood hemodynamics inside unruptured aneurysm. The coiled aneurysm is model as porous volume with porosity and permeability related to the coil size and compactness value. The results show as coil compactness increases and coil diameter decreases, the blood inflow to aneurysm volume decreases. The reduction in blood inflow to the aneurysm reduces the risk of aneurysm rupture. Also, it reduces flow circulation with the aneurysm and promote thromboses which seals aneurysm.

“…Analytical and numerical studies of the laminar flow in a porous channel with large suction along the permeable walls and a weakly oscillatory pressure performed in [12]. Friction and heat transfer for fully laminar flow in isothermal parallel plate channel completely filled with porous media are studied in [13]. Darcy equation representing the porous wall conditions is exploited in [14] to simulate fluid flow through a channel with porous walls based on finite element method.…”

Flows in channels with fluid and porous regions important to various engineering applications. A better understanding of fundamental mechanisms in the fluid flows in porous regions are needed to optimize gas bearings, air filters, thermal insulation in the specific applications. Darcy-Brinkman-Forchheimer model is used to describe the flow inside the porous domain. The finite volume method is applied to solve these equations in a porous and open domains. The capabilities of the mathematical model and computational algorithm are demonstrated using test cases from various areas of practical applications. The results of the numerical simulation of flows in porous domains are presented.

“…Akbari [9] introduced modified moving particle method in porous media (MMPP) for simulating a flow interaction with porous structures. In the field of thermal science, Hamdan [10] performed a numerical investigation on the flow and convective heat transfer characteristics for isothermal parallel plate channel filled with porous media using the finite difference method. Motsa and Animasaun [11] developed a spectral collocation method to solve a problem of unsteady heat and mass transfer past a semi-infinite vertical plate with diffusion-thermo and thermophoresis effects in the presence of suction.…”

A numerical model for non-Darcy flow, which occurs when water moves through coarse porous media under high Reynolds number, is developed. The governing equation for incompressible viscous flow through porous media is composed of a continuity equation and a momentum equation, which is the Navier-Stokes equation with an additional non-linear resistance term based on Forchheimer's law. For the discretization scheme, moving particle simulation method is employed. In order to assess the model validity, seepage experiments in different kinds of coarse porous media are implemented, and then reproducibility of the numerical results is examined. From the results, it is found that the computational flow velocities at middle part of porous media are in good agreement with experimental ones while velocities at outflow end are overestimated.
