Coronary artery disease is the end result of a complex process called atherosclerosis, which is commonly called hardening of the arteries. The pressure of blood in a coronary artery is considered to be one of the important contributors for the formation and progression of atherosclerosis. Therefore, in this paper, the impact of flow Reynolds number and percent stenosis on wall pressure and average pressure of blood near the stenosis in a part of coronary artery is studied considering laminar flow and blood as Newtonian fluid. The two-dimensional steady differential equations for conservation of mass and momentum is solved by finite difference method for Reynolds number ranging from 25 to 375 and percent stenosis from 10 to 90 %. From the study, it is revealed that for all the cases, higher the Reynolds number, higher is the concerned non-dimensional pressure. A sharp variation in dimensionless wall and average pressure has also been noted at the zone of restriction. The variation in non-dimensional wall pressure and average static pressure near the zone of stenosis is higher both for high percent stenosis and low Reynolds number.
