Abstract: 

FROM CLINICAL PRACTICE, IT IS KNOWN THAT THE CAROTID ARTERY BIFURCATION IS A ZONE WHICH IS SENSITIVE TO THE DEVELOPMENT OF LESIONS. IN THIS WORK THE COMPUTERIZED SIMULATION OF THE HEMODYNAMIC BEHAVIOR OF NON-NEWTONIAN BLOOD FLOW IN THE 3D MODEL OF CAROTID ARTERY BIFURCATION USING CFD METHOD IS STUDIED. A CONSIDERABLE APPROACH TOWARD THE REALISTIC PHYSIOLOGICAL CONDITIONS IN A PRACTICAL GEOMETRY HAS BEEN MADE. IT IS OBSERVED THAT THE LESIONS MIGHT BE APPEARED AT THE APEX OF THE BIFURCATION JUNCTION AND REPRESENTS A RISK FACTOR BY MODIFICATION THE BLOOD FLOW PATTERN, FLOW SEPARATION, RECIRCULATION REGIONS AND WALL SHEAR STRESS GRADIENTS. ALSO THE OCCURRENCE OF ANEURYSMS AT THE APEX OF BIFURCATION, WHILE THE JUNCTION ANGLE INCREASES, IS PROBABLE.
