The Mechanical Behavior of a Mammalian Lung Alveolar Duct Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model for the mechanical properties of an alveolar duct is analyzed using the finite element method. Its geometry comprises an assemblage of truncated octahedral alveoli surrounding a longitudinal ...
A Mathematical Model for the Morphology of the Pulmonary Acinus
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational method is proposed for the construction of a three-dimensional space-filling model of an acinar ventilatory unit. Its geometry consists of truncated octahedra arranged in a cuboidal ...
Relationships Between Alveolar Size and Fibre Distribution in a Mammalian Lung Alveolar Duct Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A finite element model, comprising an assemblage of tetrakaidecahedra or truncated octahedra, is used to represent an alveolar duct unit. The dimensions of the elastin and collagen fibre bundles, ...
Viscoelastic Behavior of a Lung Alveolar Duct Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A study is conducted into the oscillatory behavior of a finite element model of an alveolar duct. Its load-bearing components consist of a network of elastin and collagen fibers and surface ...
An Experimental Model of Gas Dispersion and Uptake at the Bronchial Wall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dispersion and uptake of gas boli of a range of solubilities was examined in lung airway models; first a straight tube, then a four generation network. Airway liquid lining was simulated with ...
Dispersion and Uptake in a Coiled Tube
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We have investigated the dispersion characteristics of a highly soluble tracer gas in a coiled tube lined with wet gelatine. Our experiments indicate that absorption and desorption of the gas ...
