Fluid–structure interaction analysis of hemodynamics in different degrees of stenoses considering microcirculation function

In developed countries, stenosis is the main cause of death. To investigate hemodynamics within different degrees stenoses, a model incorporating fluid–structure interaction and microcirculation function used in this paper. Microcirculation treated as seepage outlet boundary condition. Compliant arterial wall considered. Numerical simulation based on performed using finite element method. Our results indicate that (i) increasing degree makes pressure drop increase, (ii) shear stress velocity artery zone may be more sensitive than with increase percentage stenosis, (iii) there are higher flow post-stenosis region severer stenosis. This work contributes to understand for stenoses it provides detailed information function.
