Density Modulations of Zero Sound

open access: yesAnnalen der Physik, Volume 538, Issue 2, February 2026.
Zero sound is a collective mode of the strongly interacting quantum gas that propagates when atomic collisions are negligible, similarly to a plasmon. This work aims at investigating the conditions under which a density modulation associated to this collective mode travels coherently through a strongly interacting Fermi gas.

Non‐Linear Reduced Order Modelling of Transonic Potential Flows for Fast Aerodynamic Analysis

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 2, 30 January 2026.
ABSTRACT This work presents a physics‐based reduced order modelling (ROM) framework for the efficient simulation of steady transonic potential flows around aerodynamic configurations. The approach leverages proper orthogonal decomposition and a least‐squares Petrov‐Galerkin (LSPG) projection to construct intrusive ROMs for the full potential equation ...

Application of Gamification Mechanics to Computational Fluid Dynamics Seminars Using Genially

open access: yesComputer Applications in Engineering Education, Volume 34, Issue 1, January 2026.
ABSTRACT This work describes the procedure for the gamification of Computational Fluid Dynamics (CFD) seminars, with the aim of increasing student motivation and simplifying the learning and acquisition of skills related to the use of CFD tools. The seminar activity is divided into two parts: (i) autonomous work along the semester, in which students ...

Modeling of unsteady aerodynamic loads

open access: yes, 2011
Time-accurate solutions of the Euler or Navier-Stokes equations are still nowadays a computationally expensive approach for applications where a magnitude of parameters has to be investigated. This work focuses on flight dynamics-related studies.

Strategies for achieving real‐world robustness in topologically engineered surfaces with special wettability

open access: yesDroplet, Volume 5, Issue 1, January 2026.
Engineered topologies surfaces with special wettability are promising for their ability to precisely customize wetting behaviors and incorporate versatile functionalities, setting them apart from randomly structured surfaces. However, robustness and durability have been hurdles to their broad application.

Tutorial Overview: Numerical Synergy in Muffler Acoustic Design A Critical Comparison of TMM, FEM, and CFD Approaches for Transmission Loss Quantification

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
Experimental measurements reveal distinct performance boundaries: TMM achieves rapid convergence (< 2 dB error below 2000 Hz) but neglects 3D wave effects; FEA maintains < 10% deviation up to 3500 Hz with 90% reduced computational cost versus CFD; while transient CFD captures broadband attenuation trends despite 10× higher resource demands.

Experimental aeroacoustics study on jet noise reduction using tangential air injection [PDF]

open access: yes, 2011
PhDAircraft jet exhausts are a source of undesirable noise and continue to be an area of investigation driven by increasingly stringent regulation. The noise is produced by the unsteady mixing of the jet with the surrounding air and is dominated by the ...

Debye‐Scale Bipolar Structures and Their Role in the Electron Trajectory Instability at the Bow Shock

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract A number of mechanisms have been suggested to operate within the terrestrial bow shock to redistribute energy contained in the incoming solar wind flow. The majority of mechanisms involve the generation of turbulence while some are based on particle motion alone.
