Enhanced enstrophy generation for turbulent convection in low-Prandtl-number fluids [PDF]

Proceedings of the National Academy of Sciences, 2015
Significance Low-Prandtl-number thermal convection flows in liquid metals for which the temperature diffusivity is much larger than the fluid viscosity have been studied much less frequently than convective flows in air or water, despite many important applications reaching from astrophysics to energy conversion.

Finite Element Method for the Steady‐State Deformation in Strip Rolling

steel research international, EarlyView.
An explicit steady‐state elastoplastic finite element method is proposed for cold strip rolling across a wide range of thickness reductions. Combining a steady‐state formulation with static explicit stress integration, this approach achieves high accuracy and stability at a low computational cost, offering a powerful framework for robust 2D rolling ...

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing

Communications on Pure and Applied Mathematics, Volume 79, Issue 12, Page 2435-2490, December 2026.
ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Low‐Temperature Experimental Characterization of Magnetite‐Based Rock‐Bed Thermal Battery

Energy Storage, Volume 8, Issue 8, December 2026.
The graphical abstract illustrates the proposed low‐temperature magnetite‐based rock‐bed thermal energy storage (RTES) concept for greenhouse applications and the corresponding experimental configuration. During charging, thermal energy is transferred from solar collectors to the RTES and is stored as sensible heat. During discharge, the stored heat is

Influence of Thermal Boundary Conditions on Heat Transfer in Turbulent Annular Pipes

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Turbulent concentric annular pipe flow with heat transfer is investigated using the stochastic one‐dimensional turbulence (ODT) model. In the present study, annular pipe flow is investigated at fixed bulk Reynolds number ReDh=17700$\mathit {Re}_{D_{\rm h}}=17\,700$ and Prandtl number Pr=0.71$\mathit {Pr}=0.71$ using two different thermal ...

Modeling of Actively Forced Close‐Contact Melting in Latent Heat Storage Systems for Performance Evaluation

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Latent heat storage systems constitute a promising technology for thermal energy storage applications. They function by absorbing/releasing large amounts of energy during phase changes. A critical metric for these thermal storage systems is the charging and discharging rate.
