Key result
Arterial-type flows in a branching tube model produced previously unreported vortex sinks downstream of the branching port, creating stagnation regions potentially related to atheroma and thrombus formation.

Stagnation at arterial branches may promote atheroma; leaves open clinical relevance pending in vivo studies.
In vitro flow visualization demonstrates complex secondary flow patterns and stagnation points at arterial branches, which may contribute to atheroma and thrombus formation.
Pinchak et al. (1976) studied Simulated flow conditions in major vessels. Water-Plexiglas tube model was evaluated on Secondary flow patterns and vortex sinks. Arterial-type flows in a branching tube model produced previously unreported vortex sinks downstream of the branching port, creating stagnation regions potentially related to atheroma and thrombus formation.
