Effect of Endothelial Shear Stress on the Progression of Coronary Artery Disease, Vascular Remodeling, and In-Stent Restenosis in Humans: In Vivo 6-Month Follow-Up Study
Background—Native atherosclerosis and in-stent restenosis are focal and evolve independently. The endothelium controls local arterial responses by transduction of shear stress. Characterization of… Expand

BACKGROUND Although the coronary arteries are equally exposed to systemic risk factors, coronary atherosclerosis is focal and eccentric, and each lesion evolves in an independent manner. Variations… Expand

To gain insight into the details of intracoronary flow we have used computational fluid dynamic techniques to determine the velocity and wall shear stress distributions in both steady- and phasic-flow models of a curved coronary artery . Expand
A two-phase flow model for hydrogen evolution in an electrochemical cell
Hydrogen evolution, flow field and current density distribution in an electrochemical cell are investigated with a two-phase flow model. The mathematical model involves solutions of transport… Expand
Patient-specific model of lung deformation using spatially dependent constitutive parameters
Breathing-induced spatially dependent lung deformation is predicted using patient-specific elastic properties with the contact–impact analysis model. The lung geometry is derived from 4D CT scan data… Expand
A comparison of predictions and measurements of kinematic mixing of two fluids in a 2D enclosure
Abstract Buoyancy driven mixing of two fluids in a 2D closed cavity is simulated with a two-fluid model. The predictions are compared with a set of experimental data. The experiment involves flow… Expand
Prediction of fluid flow and heat transfer characteristics of turbulent shear flows with a two-fluid model of turbulence
Abstract A two-fluid model of turbulence is employed to calculate velocity and temperature characteristics of turbulent boundary layer flows over a flat plate and in heated plane and axisymmetric… Expand
A Comparison of Experimentally Measured and Theoretically Calculated Velocity Fields in a Water Model of an Argon Stirred Ladle.
Application of a hybrid model of mushy zone to macrosegregation in alloy solidification
Abstract Solidification of an aqueous ammonium chloride (NH 4 Cl–H 2 O) solution inside a two-dimensional cavity is numerically investigated using a continuum mixture mathematical model. The mushy… Expand
Effect of gravity on subject-specific human lung deformation
ABSTRACT A biomechanical model of human lung is developed and used to investigate the effect of gravity on lung deformation. The lung is assumed to behave as a poro-elastic medium with spatially… Expand
