한국형 인공심장의 시스템 및 혈류해석에 관한 연구
Study on the analysis of system and hemodynamics of the Korean artificial heart
- 발행 : 2002.05.01
초록
Flow in the blood sac of the Korean artificial heart is numerically simulated by finite element method. Fluid-structure interaction algorithm is employed to compute the 3D blood flow interacting with the sac material. The motion of the actuator is simplified by a time-varying pressure boundary condition imposed on the outer surface of the sac. Numerical solutions show that there are a strong flow into the outlet and a stagnation flow near the inlet during systole. Shear stress distribution is also delineated to assess the possibility of thrombus formation.
