RISComputational Analysis of Wall Roughness Effects for Liquid Flow in Micro-Conduits
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluid flow in microchannels or microtubes may differ in terms of wall frictional effects, and hence flow rates, when compared to macrochannels. Focusing on steady laminar fully developed flow ...
Analysis of Particle Trajectories in Aortic Artery Bifurcations With Stenosis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fluid-particle dynamics in a two-dimensonal symmetric branching channel with local occlusions representing a diseased segment of an aortic artery bifurcation has been analyzed. The validated ...
Fluid-Structure Interaction Effects on Sac-Blood Pressure and Wall Stress in a Stented Aneurysm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An aneurysm is a local artery ballooning greater than 50% of its nominal diameter with a risk of sudden rupture. Minimally invasive repair can be achieved by inserting surgically a stent-graft, ...
Effects of Major Endoleaks on a Stented Abdominal Aortic Aneurysm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Insertion of a stent-graft into an aneurysm, especially abdominal aortic aneurysms (AAAs), is a very attractive surgical intervention; however, it is not without major postoperative complications, ...
Targeted Drug Aeroso Deposition Analysis for a Four-Generation Lung Airway Model With Hemispherical Tumors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One important research area of broad interest is the development of highly efficient drug delivery systems for desired site deposition and uptake. For example, controlled drug aerosol release ...
Simulation and Analysis of High-Speed Droplet Spray Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimentally validated computer simulation model has been developed for the analysis of gas-phase and droplet characteristics of isothermal sprays generated by pressure jet atomizers. Employing ...
Laminar Flow Past Colinear Spheres With Fluid Injection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A validated computer simulation model has been developed for the analysis and design of colinear porous sphere systems in a convective stream. Using a modified and extended finite element ...
An Adjustable Triple-Bifurcation Unit Model for Air-Particle Flow Simulations in Human Tracheobronchial Airways
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new methodology for a swift and accurate computer simulation of large segments of the human lung airways is presented. Focusing on a representative tracheobronchial (TB) region, i.e., G0–G15, ...
Discussion: “Effects of Various Parameters on Nanofluid Thermal Conductivity” (Jang, S. P., and Choi, S. D. S., 2007, ASME J. Heat Transfer, 129, pp. 617–623)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a series of articles, Jang and Choi (1-3) listed and explained their effective thermal conductivity (keff) model for nanofluids. For example, in the 2004 article (1), they constructed a ...
Simulation of Particle-Hemodynamics in a Partially Occluded Artery Segment With Implications to the Initiation of Microemboli and Secondary Stenoses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational results of laminar incompressible blood-particle flow analyses in an axisymmetric artery segment with a smooth local area constriction of 75 percent have been presented. The flow ...
