文摘

First computational surgical implantation of a novel pump for Fontan circulation. Multiblock approach improves accuracy / efficiency of IBM for internal flows. IBM on fixed Cartesian grid allows simulations of flows in complex moving geometry. LES model allows accurate prediction of pathological low Re transitional flows. Pump provides desired pressure rise while keeping blood damage low.
