Abstract
In the present paper, simulation of blood flow in human heart is performed using angiography images of a healthy person. Computational fluid dynamics (CFD) is used as a vital tool to carry out the numerical simulation of many biomedical problems. Artery blockage is the most common cause of coronary artery disease. Blockage presence inside the artery breaks the continuity of blood supply to the other part of body. Therefore, 50% plaque is created in the left coronary artery to study the flow behavior of blood Three dimensional reconstruction of coronary artery has been performed using commercial image processing software MIMICS. Five inlet velocities 0.10, 0.20, 0.50, 0.70 and 0.80 m/s are taken corresponding to different flow condition of blood in human heart. . Velocity and Wall shear stress are computed and compared for the two geometrical models (Normal Vs. Blockage model). The CFD prediction of blood flow in coronary artery is useful for diagnosis, prognosis and prevention from coronary artery diseases (CAD).
