Multi-objective optimization of Resin Infusion

open access: yesAdvanced Manufacturing: Polymer & Composites Science, 2019
The present paper addresses the multi-objective optimization of the filling stage of the Resin Infusion manufacturing process. The optimization focuses on the selection of an optimal temperature profile which addresses the tradeoff between filling time ...

Concentration Sensor for Hydrogen-Methane Mixed Gas Based on Quartz Oscillator

open access: yesJournal of Thermal Science and Technology, 2007
Quartz is used in various devices, since it can be easily vibrated by the piezoelectric effect and controlled in an electric circuit. The force, which acts on the vibrating body, follows the principles of fluid dynamics; this phenomenon is explained in ...

Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

open access: yesFEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

Haptic Discrimination and Matching of Viscosity [PDF]

open access: yes, 2013
In three experiments, viscosity perception of liquids using the sense of touch was studied. The first two were discrimination experiments in which Weber fractions were determined for a number of viscosities spanning the range of what is encountered in ...

The Viscosity of Liquids [PDF]

open access: yesNature, 1930
THE viscosity of liquids is a subject which, so far as I know, has hitherto been without any general theoretical basis. No physical mechanism, for example, has ever been brought forward to account even for so simple and general a fact as the decrease of liquid viscosity with temperature, in contrast to the familiar and well explained increase of ...

Viscosity Correlation for 2,3,3,3-Tetrafluoropropene (HFO-1234yf) Based on the Extended Corresponding States Model

open access: yesJournal of Thermal Science and Technology, 2010
The viscosity of 2,3,3,3-tetrafluoropropene (HFO-1234yf) has been successfully correlated with the extended corresponding states (ECS) model for transport properties.

Radiative Bulk Viscosity

open access: yes, 2001
Viscous resistance to changes in the volume of a gas arises when different degrees of freedom have different relaxation times. Collisions tend to oppose the resulting departures from equilibrium and, in so doing, generate entropy.

Fluid turbulence and eddy viscosity in relativistic heavy-ion collisions [PDF]

open access: yesProg.Theor.Phys.Suppl.174:137-144,2008, 2007
The eddy viscosity for a turbulent compressible fluid with a relativistic equation of state is derived. Compressibility allows for sound modes, but the eddy viscosity in the shear mode is found to be the same as for incompressible fluids. For two space dimensions (which is the relevant case for the dynamics of relativistic heavy-ion collisions) the ...

Implementation of needle‐tracking technology for real‐time transrectal ultrasound‐guided interstitial gynecological HDR brachytherapy: A feasibility study

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To investigate the feasibility of adapting a commercial prostate biopsy system for transrectal ultrasound (TRUS)‐guided hybrid gynecological (GYN) high‐dose‐rate (HDR) brachytherapy (BT). Leveraging 3D‐TRUS and MR image fusion, the prototype system aims to improve real‐time needle placement accuracy.

On the vanishing viscosity limit in a disk

open access: yes, 2006
We say that the solution u to the Navier-Stokes equations converges to a solution v to the Euler equations in the vanishing viscosity limit if u converges to v in the energy norm uniformly over a finite time interval.
