Shape Morphing Programmable Systems for Enhanced Control in Low‐Velocity Flow Applications

Advanced Intelligent Systems, EarlyView.
A soft, Lorentz‐force‐driven programmable surface enables rapid, reversible shape morphing for active flow control. Integrating experimental, numerical, and modeling approaches, the system demonstrates effective modulation of near‐wall flow and momentum at low velocities, offering pathways for bio‐inspired aerodynamics and natural locomotion emulation.

Reproductive solutions for the g-Navier-Stokes and g-Kelvin-Voight equations

Electronic Journal of Differential Equations, 2016
This article presents the existence of reproductive solutions of g-Navier-Stokes and g-Kelvin-Voight equations. In this way, for weak solutions, we reach basically the same result as for classic Navier-Stokes equations.

Dispersion of First Sound in a Weakly Interacting Ultracold Fermi Liquid

Annalen der Physik, EarlyView.
 The weak‐interaction, low‐temperature region of the phase diagram of a Fermi gas the so‐called Fermi liquid regime, which has been somewhat overlooked in ultracold gases‐is investigated. Precise and measurable predictions are presented for the viscosity and dispersion of first sound to leading order in the scattering length.

The Asymptotic Stability of the Generalized 3D Navier-Stokes Equations

Journal of Applied Mathematics, 2013
We study the stability issue of the generalized 3D Navier-Stokes equations. It is shown that if the weak solution u of the Navier-Stokes equations lies in the regular class ∇u∈Lp(0,∞;Bq,∞0(ℝ3)), (2α/p)+(3/q)=2α ...

3D Resolved Computational Modeling to Simulate the Electrolyte Wetting of a Lithium‐Ion Battery Cell with 18650 Format

Batteries &Supercaps, EarlyView.
The electrolyte wetting of a lithium ion battery cylindrical cell is explored in this study with a 3D resolved continuum model that considers the exact spiral geometry found in commercial 18650 cells. The jelly roll architecture and capillary pressure are shown to be key determinants of the wetting degree and electrolyte distribution within the cell ...

An Efficient and Unified Modeling Framework for Trickle Bed Reactors: A Modular Approach

Chemie Ingenieur Technik, EarlyView.
This review gives an insight in modeling and designing techniques for multiphase catalytic reactors and their associated limitations and potential improvements. To enhance the predictive capabilities and capture events that take place on different scales, a modular approach is proposed.

Ghost effect from Boltzmann theory

Communications on Pure and Applied Mathematics, EarlyView.
Abstract Taking place naturally in a gas subject to a given wall temperature distribution, the “ghost effect” exhibits a rare kinetic effect beyond the prediction of classical fluid theory and Fourier law in such a classical problem in physics. As the Knudsen number ε$\varepsilon$ goes to zero, the finite variation of temperature in the bulk is ...

Phenomenological contact line friction coefficient

Droplet, EarlyView.
Contact line dissipation is crucial in capillary‐driven phenomena, where the resistance to contact line motion significantly influences wetting dynamics. The contact line friction coefficient μf${\mu }_{\mathrm{f}}$ emerges as a key phenomenological parameter that quantifies this dissipative behavior.
