RISFluid Movement in a Channel With Permeable Walls Covered by Porous Media: A Model of Lung Alveolar Sheet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The smallest microscopic blood vessels in the human lung are organized into sheet-like networks. These sheets form the walls of the 300 million alveoli in which air flows due to breathing. ...
Solute Distribution in the Flow in a Channel Bounded by Porous Layers: A Model of the Lung
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The tracer (indicator-dilution) technique is often used to measure the volume of interstitial water in the lung tissue. The basic hypotheses required for the validity of the formula: volume = ...
Longitudinal Dispersion of Tracer Particles in the Blood Flowing in a Pulmonary Alveolar Sheet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The analysis of G. I. Taylor on the dispersion of solutes in a circular cylindrical tube is extended to the case of flow in a channel bounded by porous layers. Creeping flow in the channel ...
Dynamic Response of Flexibly Supported Liquid‐Storage Tanks
Publisher: American Society of Civil Engineers
Abstract: A refined method is presented for evaluating the impulsive components of response of upright, cylindrical liquid‐storage tanks that are supported through a rigid circular foundation at the surface of a homogeneous, elastic ...
Fatigue-Seismic Ratcheting Interactions in Pressurized Elbows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three dynamic tests on pressurized elbows involving fatigue-ratcheting as the major failure mode are investigated. The fatigue analysis is carried out with two approaches: the first is global ...
Axisymmetric Elastic-Plastic FE Analysis of Pressurized Elbows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A variational formulation for the pure in-plane bending problem of pressurized elbows with arbitrary cross section, written in the 3-D infinitesimal displacement continuum mechanics framework, and ...
Inference of Dynamic Shear Modulus from Lotung Downhole Data
Publisher: American Society of Civil Engineers
Abstract: Downhole ground motions recorded at the Lotung Large-Scale Seismic Test (LSST) site were used in this paper to infer in-situ dynamic soil properties. The purposes were (1) to provide field evidence of nonlinear soil behavior ...
Containment Capacity and Failure Modes for Conditions beyond Design Basis
Publisher: American Society of Civil Engineers
Abstract: Under internal over‐pressure loading, experimental studies have demonstrated that the most probable ultimate failure mode of concrete containments of nuclear power plants is leakage instead of a catastrophic break. For ...
Lotung Downhole Array. II: Evaluation of Soil Nonlinear Properties
Publisher: American Society of Civil Engineers
Abstract: The characteristics of soil response during earthquake excitations, at a site in Lotung, Taiwan are identified using the Lotung large scale seismic test (LSST) data. A technique is developed to evaluate soil shear ...
Lotung Downhole Array. I: Evaluation of Site Dynamic Properties
Publisher: American Society of Civil Engineers
Abstract: The Lotung large-scale seismic test (LSST) site in Taiwan was instrumented in 1985 with an array of downhole and surface accelerometers, by the Electric Power Research Institute (EPRI), Palo Alto, Calif., and the Taiwan ...
