ABSTRACT

A numerical study has been carried out to investigate disturbances of blood flow through a stenotic coronary artery for the restrictions of 10% to 90% with the Reynolds numbers ranging from 25 to 375 for the stricture length varying from 0.1 to 2.0. Reattachment point, wall shear stress, and it's physiological aspects have been studied in detail. From this study, it is revealed that the effect of stricture length on wall shear stress and reattachment point is maximum at low stricture length. This effect gradually decreases with the increase in stricture length. This may help to stop further aggravation of plaque deposition.
