Abstract
The present paper describes the experimental work on the flow through the tapered right-angle branch model with the taper angle of 1°, in which the side branch bifurcates at 90° from the trunk. The results show that in laminar steady flow the wall shear stress reaches the maximum at the upstream corner of the side branch making significantly variation along the proximal wall in the form of a damped sinusoidal wave. Furthermore, it is suggested that the wall shear stress in the tapered right-angle branch varies more moderately than that in the straight right-angle branch. Therefore, the result of the present study distinctly explains that the tapered right-angle branch is more reasonable for human artery than the straight right-angle branch.
