ABSTRACT
By virtue of computational fluid dynamics and the fundamental principles of hemodynamics, this paper gives numerical simulations and analyses of blood flow in the human thoracic aorta. The distributive features of velocity and pressure of the blood flow are obtained with the use of initial parabolic pulsatile blood flow. The numerical results show that, due to the angularity of thoracic aorta and due to the branch arteries, the distributions of velocity and pressure display marked difference, especially for the horizontal velocity, in the thoracic aorta connecting with the second and third branch artery, which indicate the place where thoracic aortic dissection often happens.
