Studies in Applied Mathematics, Volume 156, Issue 4, April 2026.ABSTRACT The system describing the dynamics of a compressible isentropic fluid exhibiting viscosity and internal capillarity in one space dimension and in Lagrangian coordinates, is considered. It is assumed that the viscosity and the capillarity coefficients are nonlinear smooth, positive functions of the specific volume, making the system the most ...

Analysis of Thermal Dynamics of Floating Photovoltaic Systems
Solar RRL, Volume 10, Issue 6, 29 March 2026.A scalable methodology couples computational fluid dynamics‐derived wind decay functions with a dynamic heat transfer model to capture spatial temperature variations across large floating photovoltaic systems and is validated with data from the Netherlands floating photovoltaic systems (FPV) site.

Solar RRL, Volume 10, Issue 6, 29 March 2026.Fluid‐dynamic control of supersaturation is unlocked to resolve the trade‐off between film continuity and crystal growth in perovskite bar‐coating. By utilizing a thermally driven circulation loop that suppresses excessive evaporation, we realize giant‐domain films at reduced temperatures.

Non‐Monotonic Dependence of Mixing on Phase Saturation in 3D Porous Media
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Two‐dimensional (2D) experiments and simulations are commonly used as a representations of three‐dimensional (3D) flow and transport in porous media. However, these 2D approaches may yield misleading results due to fundamental differences in flow dynamics between 2D and 3D systems.

Dual Variational Problems and Action Principles for Chen–Lee and Hopf–Langford Systems
Mathematical Methods in the Applied Sciences, Volume 49, Issue 4, Page 2456-2462, 15 March 2026.ABSTRACT We describe the construction of dual variational principles and action functionals for nonlinear dynamical systems using a methodology based on the dual Lagrange multiplier formalism and a convex optimization approach, to derive families of dual actions that correspond to the given nonlinear ordinary differential system.

International Journal for Numerical Methods in Engineering, Volume 127, Issue 5, 15 March 2026.ABSTRACT This work presents novel structure‐preserving formulations for stable model order reduction in the context of time‐domain room acoustics simulations. A solution to address the instability in conventional model order reduction formulations based on the Linearized Euler Equations is derived and validated through numerical experiments.
