TLDR
A simple method is given for extending across junctions the numerical methods previously used to study fluid flow in nonuniform, nonbranching, distensible tubes, suggesting that the ratio of downstream to upstream cross-sectional areas and the pressure wave velocity ratio in mammals are optimal for energy transfer across the junction.About:

Optimization of diameters and bifurcation angles in lung and vascular tree structures
TL;DR: An optimization model is described for lung and vascular tree structures that takes into account all types of steady flow, e.g. turbulent and laminar flow, and predicts which structural changes will occur among different parts of trees having different types of flow.

Pathological—anatomical study concerning the geometry and atherosclerosis of the carotid bifurcation
TL;DR: It is concluded that a non-optimal area ratio of a carotid bifurcation seems to be a factor in atherogenesis.

Mathematical model representing blood flow in arteries.
John H. Gerrard,Linda A. Taylor +1 more
TL;DR: A method is presented which bases the skin friction on a linear approximation, but within this limitation uses a value which is correct in magnitude and phase, and the sensitivity of the results to changes in the friction term is demonstrated.

Arterial Pulse Transmission Characteristics
TL;DR: In this paper, the authors show that the arterial tree structure and geometric non-uniformity of the vascular tree can give rise to differences in observed pressure and flow waveforms in different anatomic locations in the vascular system.

An Elastic Tube Theory of Pulse Transmission and Oscillatory Flow in Mammalian Arteries
TL;DR: In this article, the authors developed the concept of a thin walled elastic tube as a rough working model of an artery, and from a solution of the equations of motion of such a tube, filled with viscous liquid, a number of relationships are deduced that can be tested experimentally.
