Abstract

An electrochemical surface shear stress measurement was applied to a model of unilateral arterial stenosis. The unilateral stenosis model consisted of a removable stenosis plug which was placed inside an electrochemical shear stress measurement test section containing 100 electrodes. Three dimensional wall shear stress distribution was measured under conditions of steady flow. We found a characteristic high and low wall shear stress distribution pattern beginning immediately downstream of the unilateral stenosis plug. Furthermore, we observed remarkable high shear stress regions on the opposite wall both up- and downstream of the stenosis; as well as on both side walls upstream of the stenosis.
