Pulmonary artery stenosis is closely related to hemodynamics. In this paper, the laminar and turbulent flows in the same three-dimensional model of pulmonary artery stenosis are numerically calculated by using fluid-structure interaction, and the obtained maximum velocity, pressure and wall shear stress are compared and analysed. The numerical results show that the hemodynamic parameters of laminar flow model are slightly higher than those of k-ε turbulence model. Specially, the wall shear stress at both ends of stenosis is more sensitive to laminar flow model. This study provides the effects of laminar flow and k-ε turbulence on pulmonary artery hemodynamics. It gives a basis for the follow-up realistic hemodynamic numerical simulation of pulmonary artery model and has a guiding significance for clinical diagnosis and treatment, and promotes the development of the combination of mechanics and medicine.
