چکیده

A one dimensional model of the pulmonary arterial network along with systemic circulation was introduced to quantify the human pulmonary artery hemodynamics. Alumped parameter model of the right ventricle was used as the inlet boundary condition. A time varying elastance related thevolume and pressure of the right ventricle was imposed in themodel. By using a four element Windkessel model, blood flow rate throughout the right ventricle was in hand. An asymmetricstructured tree was chosen as the outlet boundary conditions. Simulation was based on solving one-dimensional equations ofconservation of mass and momentum by using finite volume method. Blood flow rate, pressure and velocity through eachartery were calculated. Parameters of the structured tree werechanged to see their effect on the behavior of pulmonary circulation. There was a good agreement between the results of this model and previous results. Meanwhile, a scaling factor was imposed for considering the effect of respiration and comparison the flow rate through arteries between inspiration and expiration.

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.
