A Level Set Method Coupled With a Volume of Fluid Method for Modeling of Gas-Liquid Interface in Bubbly Flow

John Richard Thome, Bogdan Alexandru Nichita, Iztok Zun

This paper describes the implementation of a 3D parallel and Cartesian level set (LS) method coupled with a volume of fluid (VOF) method into the commercial CFD code FLUENT for modeling the gas-liquid interface in bubbly flow. Both level set and volume of ...

3D finite element model of semi-solid permeability in an equiaxed granular structure

Roland Logé

A multi-domain finite element formulation has been applied to determine the semi-solid permeability of an equiaxed granular structure. The granular model was constructed from a Voronoï tessellation algorithm. The liquid-solid interface is represented impli ...

An Improved CFD Tool to Simulate Adiabatic and Diabatic Two-Phase Flows

Bogdan Alexandru Nichita

With increasing computer capabilities, numerical modeling of two-phase flows has developed significantly over the last few years. Although there are two main categories, namely 'one' fluid and 'two' fluid methods, the 'one' fluid methods are more commonly ...

Dynamic calibration of our sense of time

Fosco Bernasconi

An accurate sense of time contributes to functions ranging from the perception and anticipation of sensory events to the production of coordinated movements. However, accumulating evidence demonstrates that time perception is subject to strong illusory dis ...

Identification of epidermal pdx1 expression discloses different roles of notch1 and notch2 in murine kras-induced skin carcinogenesis in vivo

Freddy Radtke

BACKGROUND: The Ras and Notch signaling pathways are frequently activated during development to control many diverse cellular processes and are often dysregulated during tumorigenesis. To study the role of Notch and oncogenic Kras signaling in a progenitor ...

The role of perspective functions in convexity, polyconvexity, rank-one convexity and separate convexity

Bernard Dacorogna

Any finite, separately convex, positively homogeneous function on

Approximating the Gaussian multiple description rate region under symmetric distortion constraints

Suhas Diggavi

We consider multiple description coding for the Gaussian source with K descriptions under the symmetric mean squared error distortion constraints. One of the main contributions is a novel lower bound on the sum rate, derived by generalizing Ozarow’s well-k ...

Eikonal approximation in AdS/CFT: Conformal partial waves and finite N four-point functions

We introduce the impact parameter representation for conformal field theory correlators of the form A similar to (O1O2O1O2). This representation is appropriate in the eikonal kinematical regime, and approximates the conformal partial wave decomposition in ...

Structure-property relationships: Polymorphism, solvates, and clay behavior in the one-dimensional coordination polymer chains [Ag(L)(NO3)](H2O)n, L = ethanediyl bis(isonicotinate), n = 0, and 2

The system AgNO3 and L (L = ethanediyl bis(isonicotinate)) yielded so far five different compounds from a THF/H2O mixture (or acetonitrile) when reacted in a ratio 1:1. Three solvent-free compounds possess the same chemical composition, [Ag(L)NO3], but dif ...

Synthèse d'images moiré

Sylvain Chosson

We explore a new approach for synthesizing moiré images that can be used for authentication of documents. For synthesizing moiré images, we need two layers: a base layer made of replicated bands or parallelograms and a revealing layer made of transparent l ...
