ABSTRACT

Impact of stenosis length on flow of blood through rectangular stenosed coronary artery has been investigated in case of non dimension stenosis lengths of 0.1, 0.5, 1.0 and 2.0 for the restriction of 50% (by diameter) and Reynolds number of 200. Effect on streamline contour and wall shear stress has been discussed and presented along with its possible physiological aspects. It is revealed that the wall shear stress is dependent upon the stenosis length but reattachment length is relatively independent of stenosis length.
