Abstract

Owning to important role of the CARDIOVASCULAR SYSTEM in the human body and increase of cardiovascular diseases day by day, in this study we try to simulate a system of arteries by using one dimensional numerical modeling. For the first time in the one dimensional simulation, we use the FINITE VOLUME method for discretization of Navier-Stocks equations coupled with the state equation. In order to develop the outflow boundary condition, we use a kind of lumped model called arteriole structure tree.Results of this study are verified by results of another ONE DIMENSIONAL MODELING, i.e., the characteristic method, showing that FINITE VOLUME method is able to demonstrate characteristics of BLOOD FLOW in arteries. Normal pressure and flow profiles in main systemic arteries are determined, and it is found that the pressure profile becomes steeper with distance from the heart, which is in agreement with physiological patterns. Furthermore, we show that when elasticity of arteries is increased in arteriosclerosis disease, systolic pressure increases, yet diastolic pressure decreases. Finally, according to available results it is clear that the FINITE VOLUME method is useful to simulate the CARDIOVASCULAR SYSTEM numerically and one dimensionally.
