Observation of Bulk Plasticity in a Polycrystalline Titanium Alloy by Diffraction Contrast Tomography and Topotomography
J. C. Stinville, W. Ludwig, P. G. Callahan +4
The mechanical properties of polycrystalline metals are governed by the interaction of defects that are generated by deformation within the 3D microstructure. In materials that def…
P-type behavior of CrN thin films by control of point defects
Arnaud le Febvrier, Davide Gambino, Fabien Giovannelli +5
We report the results of a combined experimental and theoretical study on nonstoichiometric CrN1+d thin films grown by reactive magnetron sputtering on c-plane sapphire, MgO (100)…
Time resolved evolution of the 3D nanoporous structure of sintered Ag by X-Ray nanotomography: role of the interface with a copper substrate
Kokouvi Happy N'Tsouaglo, Xavier Milhet, Jérôme Colin +6
The evolution of the nanoporous structure of cylindrical sintered silver samples during high temperature aging, ranging from 200 {\textdegree}C to 350 {\textdegree}C for 350 min, i…
Clustering to the Fewest Clusters Under Intra-Cluster Dissimilarity Constraints
Jennie Andersen, Brice Chardin, Mohamed Tribak
This paper introduces the equiwide clustering problem, where valid partitions must satisfy intra-cluster dissimilarity constraints. Unlike most existing clustering algorithms, equi…
MONITOR: A Multimodal Fusion Framework to Assess Message Veracity in Social Networks
Abderrazek Azri, Cécile Favre, Nouria Harbi +2
Users of social networks tend to post and share content with little restraint. Hence, rumors and fake news can quickly spread on a huge scale. This may pose a threat to the credibi…
Shock-induced cavitation and wavefront analysis inside a water droplet
Luc Biasiori-Poulanges, Hazem El-Rabii
The objective of the present study is to develop a basic understanding of the interaction of shock waves with density inhomogeneities. We consider here the particular instance of a…
The triple Leidenfrost effect: preventing drops coalescence on a hot plate
F. Pacheco-Vazquez, J. L. Palacio-Rangel, R. Ledesma-Alonso +1
We report on the collision-coalescence dynamics of drops in Leidenfrost state using liquids with different physicochemical properties. Drops of the same liquid deposited on a hot c…
Including acoustic modes in the vortex-sheet eigenbasis of a jet
Matteo Mancinelli, Eduardo Martini, Vincent Jaunet +1
Vortex-sheet models of jets are widely used to describe the dynamics of modes, such as the Kelvin-Helmholtz instability and guided acoustic waves. However, it is seldom pointed out…
Numerical investigation of three-dimensional partial cavitation in a Venturi geometry
Camille Gouin, Carlos Junqueira-Junior, Eric Goncalves da Silva +1
Sheet cavitation appears in many hydraulic applicationss and can lead to technical issues. Some fundamental outcomes such as the complex topology of 3-Dimensional cavitation pocket…
Self-similar mechanisms in wall turbulence studied using of resolvent analysis
U. Karban, E. Martini, A. V. G. Cavalieri +2
Self-similarity of wall-attached coherent structures in a turbulent channel at is explored by means of resolvent analysis. In this modelling framework, coherent structur…
Analysis of Lundgren's matched asymptotic expansion approach to the Kármán-Howarth equation using the EDQNM turbulence closure
Marcello Meldi, John Christos Vassilicos
In this paper we investigate whether the features of the non-equilibrium cascade, which have been identified in recent studies using high-fidelity tools, can be captured in the cas…
A meshless method for the solution of incompressible flow equations
Stéphane Couturier, Hamou Sadat
This article reports on the efficiency of a co-located diffuse approximation method coupled with a projection algorithm for the solution of two and three-dimensional incompressible…
Resolvent-based modeling of turbulent jet noise
Ethan Pickering, Aaron Towne, Peter Jordan +1
Resolvent analysis has demonstrated encouraging results for modeling coherent structures in jets when compared against their data-educed counterparts from high-fidelity large-eddy…
3D Fluorescent Mapping of Invisible Molecular Damage after Cavi-tation in Hydrogen Exposed Elastomers
Xavier P. Morelle, Gabriel E. Sanoja, Sylvie Castagnet +1
Elastomers saturated with gas at high pressure suffer from cavity nucleation, inflation, and deflation upon rapid or explosive de-compression. Although this process often results i…
