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.
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.
