The aim of the paper is to propose a mathematical model for the flow of the interstitial fluid in a lymph node, which main feature is the presence of a porous bulk region with a very low permeability, surrounded by a thin channel where the fluid can flow freely. The flow is driven by a pulsatile pressure gradient. An explicit solution is found in the case of a laminar flow in a simplified situation, while some finite element simulations are presented in a more realistic geometry.

淋巴结中脉动液体流动的模型

本文的目的是提出一种淋巴结间质液流动的数学模型，其主要特征是存在渗透性非常低的多孔块体区域，周围有一个薄通道，液体可以在其中流动自由地。流动由脉动压力梯度驱动。在简化情况下的层流情况下找到了显式解，而一些有限元模拟则以更真实的几何形状呈现。
