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.

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 ...

Quantifying the Form‐Flow‐Saltation Dynamics of Aeolian Sand Ripples

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 10, October 2025.
Abstract Ripples are the most fundamental and ubiquitous aeolian bedforms formed on sandy surfaces, but their small size and fast response times make them inherently difficult to measure. However, these attributes also make ripples excellent flow indicators, and they have been used extensively in planetary locations for this purpose.

Velocimetry of red blood cells in microvessels by the dual-slit method: Effect of velocity gradients [PDF]

open access: yes, 2012
The dual-slit is a photometric technique used for the measurement of red blood cell (RBC) velocity in microvessels. Two photometric windows (slits) are positioned along the vessel.

Description and Convergence Order Analysis of the Finite Element‐Volume Spatial Discretization Method

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 97, Issue 9, Page 1189-1208, September 2025.
This article presents the principles of Finite Element‐Volume discretization and conducts an analysis of its properties and convergence orders. The discretization ensures local mass conservation, second‐order convergence for velocity, and first‐order convergence for pressure.

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 ...
