%X As we know, the regular arterial flow is in the laminar flow regime. The blood flow properties, particularly, the shear stresses along the blood vessel, and the sites where atherosclerosis develops, have attracted tremendous researches in recent decades. It has been well known that the oscillating and low shear stresses play an important role in the development of vascular lesions. Unsteady irregular stress distributions are likely to prevail at the curved and bifurcated vessels with side branches, where, due to complicated geometries, blood flows always contain flow separation or secondary motions difficult to be simulated and understood in fluid mechanics. In this paper, the past studies on the transient multi-dimensional blood flows in arterial stenosis or in arterial geometries relevant in the conditions of atherosclerosis are reviewed. We also make suggestions for the future possible studies of circulatory vascular flows and wish to provide some food for though for further designs of bio-medical devices.
