摘要
In this paper, a method was proposed that the wall shear stress of arterycould be determined by measuring the centerline axial velocity and radial motion of arterial wallsimultaneously. The method is simple in application and can get higher precision when it is used todetermine the shear stress of arterial wall in vivo. As an example, the shear stress distribution inperiodic oscillatory flow of human carotid was calculated and discussed. The computed results showthat the shear stress distribution at any given instant is almost uniform and will be zero at thecenterline and tends to maximum at the vessel wall.
