چکیده
an abnormal narrowing of a blood vessel stenosis is investigated in this study the present work provides a simulation of blood in a vessel with 50%stenosis in addition the effects of tissue surrounding the blood vessel on displacements and stresses in stenotic vessel wall are considered the analysis consists of two distinct but coupled procedures: first,a fluid-dynamics analysis including a calculation of the velocity field and pressure distribution in the blood variable in time and in space: second ,a mechanical analysis of the deformation of the tissue and vessel to do so COMSOL multiphysics as a powerful software was used to simulate the wall-blood interaction the diameter of vessel is 8millimeters and the blood assumed to be a newtonian and incompressible fluid in addition to the walls of vessel and surrounding biological tissue were assumed to be a hyper -elastic material .کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
