Abstract :
In the present work, the hemodynamic field of an occluded artery is studied experimentally. 2D D.P.I.V measurements are presented regarding the statistically mean and turbulent flow field created in an artery having a double stenosis with over 75% occlusion. In this manuscript, the steady state case is considered. Experimental results show the influence of the stenoses on the formation of recirculation zones and the effect of flow characteristics on the shear stresses developing in the artery model.
