    Abstract: The present paper describes the experimental implemented work on the flow situation through a branch model having a daughter tube bifurcated from a parent tube at 45 deg. Experiments have been conducted utilizing an electrochemical method. The results show that, even in steady flow, the wall shear stress along the proximal wall in the daughter tube varies significantly with position in the form of a damped sine wave. For pulsating flow at the nondimensional pulsating frequency of α = 6.6, the above mentioned tendency appears to be severe, and the distribution of its amplitude in pulsating flow is similar to that of wall shear stress in steady flow.
