대동맥 분기부에 발생한 협착부의 혈액 유동 특성 = Blood Flow Characteristics in the Abdominal Aortic Bifurcation with Stenosis

다국어 초록 (Multilingual Abstract)

The three dimensional steady flows of blood and blood analogue fluids in the abdominal aortic bifurcation are simulated using the finite volume method. The objective of this investigation is to understand the generation and progression of specific atherosclerosis from a hydrodynamic point of view. Due to complexity of blood in conducting experimental study, aqueous polymer solution are used as the substitutional fluids. For comparison purpose of the flow characteristic of blood and substitutional fluids, rheologically different fluids such as water soluble polymers of Carbopol-934 and Separan AP-273 are employed for the numerical simulation. In order to understand the role of hydrodynamic in the formation and development of atherosclerosis lesions flow velocities, pressures and shere stresses along the vessel are calculated for steady flows
