  • Title: Phasic and spatial pressure measurements in a femoral artery branch model for pulsatile flow.
    Author: Back LH, Cho YI, Crawford DW.
    Journal: J Biomech Eng; 1986 Aug; 108(3):251-8. PubMed ID: 3747469.
    Abstract:
    Phasic and spatial time-averaged pressure distributions were measured in a 60-deg femoral artery branch model over a large range of branch flow ratios and at physiological Reynolds numbers of about 120 and 700. The results obtained with an in-vivo like flow wave form indicated spatial adverse time average pressure gradients in the branch vicinity which increased in magnitude with branch flow ratio, and the importance of the larger inertial effects at the higher Reynolds numbers. Pressure losses in the branch entrance region were relatively large, and corresponding flow resistances may limit branch flow, particularly at higher Reynolds numbers. The effect of branch flow was to reduce the pressure loss in the main lumen.
