本文采用非线性、一维动脉血流数值模型研究了血液中粘性剪切和血管壁中粘性阻尼之间的能量耗散分布。忽略由于锥形和振荡流引起的附加损失，壁面中耗散的能量约为。股动脉18例，胸上主动脉115例。当股动脉包括锥形和振荡流效应时，血液耗散的能量大约加倍，壁与血液耗散的比率减半，为116。
The non-linear, one-dimensional numberical model of arterial blood flow has been used to examine the distribution of energy dissipation between viscous shear in the blood and viscous damping in the vessel wall. Neglecting additional losses due to taper and oscillatory flow, the energy dissipated in the wall was ca. 1 8, for the femoral artery and 1 15, for the upper thoracic aorta, of that dissipated by the blood. When the taper and oscillatory flow effects were included for the femoral artery, the energy dissipated by the blood was approximately doubled and the ratio of wall to blood dissipation halved, to 1 16.
