Stabilité d’un écoulement cisaillé modélisant la crème de vase [PDF]

open access: yes, 2010
Afin d'améliorer la compréhension de la mise en suspension de la vase au fond des estuaires, une étude paramétrique de la stabilité d’un écoulement bidimensionnel cisaillé modélisant deux couches fluides miscibles de masse volumique et de viscosité ...

3D SR‐μXCT analysis for lithology detection: Application to Ryugu sample A0159

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 11, Page 2623-2654, November 2025.
Abstract Extraterrestrial breccia samples are formed through impact‐related processes that combine the fragments of distinct lithologies. As such, they are valuable indicators of the complex formation and evolution history of planetesimals in our solar system.

Influence of Impeller Geometry on the Unsteady Flow in a Centrifugal Fan: Numerical and Experimental Analyses

open access: yesInternational Journal of Rotating Machinery, 2007
The aim of this study is to evaluate the influence of design parameters on the unsteady flow in a forward-curved centrifugal fan and their impact on the aeroacoustic behavior. To do so, numerical and experimental studies have been carried

Discontinuous Galerkin schemes for the Stokes problem [PDF]

open access: yesEPJ Web of Conferences
Our aim is to develop a robust and flexible code to simulate flows in nuclear core reactors. Discontinuous Galerkin schemes are thus proposed here to solve the Stokes problem, which stands as a fundamental element in fluid mechanics.

Stall Margin Improvement in an Axial Compressor by Continuous and Pulsed Tip Injection

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2022
Stall and surge are strong limitations in the operating range of compressors and thus one of the major limits of jet engine performance. A promising way to push the stability limit of compression machines is to inject a small amount of flow at the blade ...

Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties

open access: yesAdvanced Functional Materials, Volume 35, Issue 42, October 15, 2025.
This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...

Synchrotron 4D X‐Ray Computed Tomography of a Porous Limestone: Influence of Porosity on Deformation Mechanisms at Multiple Scales

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract This study investigates the relationship between deformation mechanisms and heterogeneity of porosity of a porous carbonate rock across several scales. The Saint Maximin limestone (SML), characterized by centimeter‐scale alternations of dense and porous zones, serves as a model rock to examine the evolution of deformation modes.

Micro-continuum modeling of biofilm growth coupled with hydrodynamics in OpenFOAM

open access: yesSoftwareX
Biofilm growth is a complex phenomenon that couples species transport and reactions with fluid flow dynamics. Simulating these processes in complex geometries remains challenging due to the different time and space scales, as well as the associated ...
