Blood flow reduced-order modeling across macroscopic through mesoscopic scales

Résumé

We propose a hemodynamic reduced-order model bridging macroscopic and mesoscopic blood flow circulation scales from small arteries to capillaries. Representative network geometries are generated by means of stochastic growth algorithms constrained by statistical morphological and topological principles and are mathematically described by graphs. Different compliant structural models with respect to pressure loads are used depending on vessel walls thicknesses and structures. Nonlinear rheological properties of blood are also included in the model. Dynamic network responses are computed for different conditions. The computational model quantifies small-scale flow pulsatility, which has wide-ranging physiological influences.
