Free Surface Waves in Electrohydrodynamics With a Prescribed Vorticity Distribution

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 7068-7081, 15 May 2026.
ABSTRACT Traditionally, the study of free surface flows assumed irrotationality to simplify matters, and the results seemed to have great success, notably with the Korteweg‐de Vries(KdV) equation. In the past decade, there have been attempts to remove this seemingly strong condition and replace it with a global constant vorticity equivalent to a linear

Distribution, Formation, and Evolution of Subsurface Secondary Acoustic Ducts From Global Ocean Modeling and Observations

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Monthly mean reanalysis from assimilating global ocean circulation models spanning 27 years is used to study subsurface secondary acoustic ducts, which provide waveguides for the transmission of mid‐frequency sound. A systematic diagnosis of secondary ducts from monthly mean temperature and salinity fields characterizes their distribution and ...

Interaction of Ocean Currents and Seamounts: Near‐Bottom Dynamics Around Atlantis II

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract This work investigates through a modeling exercise the interaction of a strong, surface current with isolated seamounts, focusing on the Gulf Stream and Atlantis II, one of the New England Seamounts. The roles of bathymetric details and model resolution are investigated with three simulations that consider realistic realizations of the ...

Surrogate Quantum Circuit Design for the Lattice Boltzmann Collision Operator

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 4, 28 February 2026.
ABSTRACT This study introduces a framework for learning a low‐depth surrogate quantum circuit (SQC) that approximates the nonlinear, dissipative, and hence non‐unitary Bhatnagar–Gross–Krook (BGK) collision operator in the lattice Boltzmann method (LBM) for the D2Q9$$ {D}_2{Q}_9 $$ lattice.

A Jacobian‐Free Newton‐Krylov Method for Cell‐Centred Finite Volume Solid Mechanics

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.
ABSTRACT This study proposes a Jacobian‐free Newton‐Krylov approach for finite‐volume solid mechanics. Traditional Newton‐based approaches require explicit Jacobian matrix formation and storage, which can be computationally expensive and memory‐intensive.

Shrouded Wind and Water Turbine Analytical Model Extensions for Tip Gaps, Center Bodies, and Flow Blockage

open access: yesWind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This paper provides improvements to a previously presented simple, accurate, lower order analytical model for predicting the performance of horizontal‐axis shrouded turbines for a wide range of shroud airfoil shapes varying in length, camber, and thickness. The new, extended model incorporates explicit quantitative predictions of those effects

A Pull‐Out Mooring Wave Energy Converter: Design, Analysis, and Application

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
A pull‐out mooring wave energy converter (POM‐WEC) with a high‐performance electromagnetic power take‐off system efficiently converts low‐frequency wave excitation into high‐speed rotor motion, enabling reliable energy harvesting in real marine environments.

Vortex Line Density in a Superfluid Turbulent Wake in the Zero Temperature Limit

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
The quasiclassical conjecture for quantum turbulence in a pure superfluid straightforwardly leads to the definition of the superfluid Reynolds number, Res=ud/κ$Re_s=ud/\kappa$, and suggests that the effective quantum viscosity should be of the order of the circulation quantum κ$\kappa$.

A study of a free convective boundary layer using a parcel‐based Lagrangian model

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 152, Issue 774, January 2026 Part A.
We study the development of a convective boundary layer forced by surface heating and growing into a stably stratified atmosphere above. We compare our results with several recent comprehensive direct numerical simulation (DNS) studies and find broad agreement, and often close quantitative agreement, despite fundamental differences in the numerical ...

Large‐Amplitude Periodic Solutions to the Steady Euler Equations With Piecewise Constant Vorticity

open access: yesStudies in Applied Mathematics, Volume 156, Issue 1, January 2026.
ABSTRACT We consider steady solutions to the incompressible Euler equations in a two‐dimensional channel with rigid walls. The flow consists of two periodic layers of constant vorticity separated by an unknown interface. Using global bifurcation theory, we rigorously construct curves of solutions that terminate either with stagnation on the interface ...
