A numerical study has been carried out to investigate disturbances of blood flow through coronary artery with two rectangular stenoses for the restrictions of 10 to 90 % with the Reynolds numbers ranging from 25 to 375. Wall pressure, average pressure, flow characteristics, and its physiological aspects have been studied in detail. The non-dimensional pressure drop is higher for higher stricture length of rectangular stenosis. Atherosclerotic plaque formation tends to start from very low flow Reynolds number of 25 and 50 with 50 % restriction. For Reynolds numbers of 100 and above, it starts at 30 % stenosed condition. No applicable magnitude of variation between wall pressure and average pressure is noted. The effect of stricture length has been found no impact on the reattachment length.
