Summary

Velocity profiles of pulsatile flow in a tapered U-bend which is a model of aortic arch are visualized and measured by using a laser-induced fluorescence (LIF) method. Three-dimensional numerical simulation based on Navier-Stokes equation is carried out for the same boundary geometry and flow condition as those used in the experiment of LIF. Velocity profiles of the main flow between experimental data and calculation results are compared and cause of difference in velocity profile between them is discussed. In the numerical calculation for the tapered U-bend, change in secondary flow in the cross-section from inlet to outlet of the bend is shown and behavior of vortex pair is considered.
