Abstract

The present paper describes the experimental work on the flow through the tapered branch model with the taper angle of 1°, in which a side branch bifurcates at right angle from a trunk. The results show that in steady flow the wall shear stress reaches a maximum at the upstream corner of the side branch and varies significantly with position along the proximal wall in the form of a damped sine wave. Furthermore, the wall shear stress in the tapered branch seems to vary more moderate than that in the parallel straight branch. Therefore, the results of the present study suggest that the tapered branch is more suitable to human artery than the parallel straight branch.
