This computational fluid dynamics study provides numerical analysis of flow in constricted tubes at low Reynolds numbers, which may help in understanding the hemodynamics of arteriosclerosis.
Should not change arteriosclerosis management; leaves open hemodynamic modeling from low-Re CFD for future validation.
With an objective to understand arteriosclerosis, the blood flow in a circular cylindrical tube with a local constriction is analyzed. Numerical results are presented for the streamlines and the distributions of velocity, pressure, vorticity, and shear stress in the Reynolds number range 0–25. These results have applications to other fluid-mechanical problems such as gauges for velocity measurements, etc.
