2D Bifurcating Artery

Created using ANSYS 14.5

Problem Statement

...

We’ll ignore 3D effects and use the following idealized 2D geometry. All dimensions are shown in mm.

Image Added

Consider the following two plaque configurations. Model the plaque as a circular arc with a diameter of 3 mm except the one that spans two limbs whose dimensions are shown below.

Image Added

You also need to study the effect of a blood clot in the right branch (in addition to the plaque) as shown in the figure below. Assume that the blood clot has a diameter of 1 mm.

FLUENT Inputs

• Steady 2D flow
• Outlet gauge pressure = 0 Pa
• Density = 1000 kg/m³
• Coefficient of viscosity = 0.001 kg/(m-s)
• Adjust inlet velocity to get a Reynolds no. of 400.
