A Computationally Efficient Dynamic Grid Motion Approach for Arbitrary Lagrange–Euler Simulations

Fluids, 2023
The present article addresses the topic of grid motion computation in Arbitrary Lagrange–Euler (ALE) simulations, where a fluid mesh must be updated to follow the displacements of Lagrangian boundaries.

SuperCam Raman Activities at Jezero Crater, Mars: Observational Strategies, Data Processing, and Mineral Detections During the First 1000 Sols

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract The Mars 2020 Perseverance rover introduced Raman spectroscopy to in situ planetary exploration for the first time when it landed in Jezero crater on Mars in February 2021. The SuperCam instrument onboard Perseverance is a multi‐analytical tool capable of acquiring time‐resolved Raman data from Martian targets at standoff distances of a few ...

Numerical study of solid particle axial mixing in a fixed cylindrical drum with rotating paddles [PDF]

, 2012
Axial mixture characterization is a wide spread problem in granular particle blending processes such as in an horizontal drum mixer. The homogeneous mixture of particles is obtained by blending the particles via rotating paddles in a fixed cylindrical ...

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

Meteoritics &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.

Small-width wall-attached Coandǎ jets for flow control

Flow, 2023
The flow dynamics of small-width wall-attached jets generated by a Coand-effect nozzle is investigated by unsteady Reynolds-averaged Navier–Stokes simulations. The data are validated by comparison with hot-wire velocity measurements performed on the same

Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties

Advanced 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 ...

From shear stress to wall pressure spectra: a semi-analytical approach to account for mean pressure gradients in turbulent boundary layers

Acta Acustica, 2022
This study offers a semi-analytical means to compute the wall pressure spectra beneath a turbulent boundary layer depending only on the latter’s Kármán number and dimensionless pressure gradient.
