Optimal Nanoparticle Size in SiO₂/Al₂O₃‐Water Nanofluids for Enhancing Intercooler Thermal Enhancement: A Conjugate Heat Transfer Study

Energy Science &Engineering, Volume 14, Issue 3, Page 1387-1397, March 2026.
The simulation shows that the comprehensive heat transfer effect of using nanofluids as cooling liquid is greater than 1.30 nm SiO2/water and 40 nmAl2O3/water nanofluids have the best heat transfer enhancement effect, while all nanofluids of 30 nm Al2O3/water have the best heat transfer enhancement effect.

The von Neumann Stability Analysis of the Fixed‐Stress Schemes in Poroelastodynamics

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 4, Page 1939-1951, March 2026.
ABSTRACT We investigate splitting schemes based on the fixed‐stress sequential approach for poroelastodynamic problems. To assess numerical stability, we perform the von Neumann stability analysis on several fixed‐stress schemes for poroelastodynamics, including staggered, stabilized, and iterative methods. Our analysis reveals that while the staggered

Three‐Dimensional Simulation of Crack Initiation in ice Shelves at Pinning Points

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Ice shelves are large ice masses floating on the ocean that are still connected to the inland ice of a glacier. Due to high elevations in the bathymetry, the ice shelf can be partially grounded. These areas are called ice rises that act as pinning points.

Analysis and modeling of fractional Mandelbrot scaling for parameterization-invariant theories for mechanical systems

Physics Open
This study presents a comprehensive analysis and modeling framework that integrates Mandelbrot's fractal scaling with fractional variational principles to advance the understanding of parameterization-invariant theories for mechanical systems.

Regularity Properties of Solutions of a Model for Morphoelastic Growth in the Presence of Nutrients in One Spatial Dimension

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Regularity properties of solutions for a class of quasi‐stationary models in one spatial dimension for stress‐modulated growth in the presence of a nutrient field are proven. At a given point in time the configuration of a body after pure growth is determined by means of a family of ordinary differential equations in every point in space ...

Enhancing Robustness in Finite‐Strain Crystal Plasticity: An Interior Point Method With Sequential Rotation Updates

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Crystal plasticity simulations offer insights into the anisotropic deformation of polycrystalline materials such as metals and alloys. However, rate‐independent crystal plasticity models encounter the Taylor ambiguity, where the active slip systems and plastic slip magnitudes are not uniquely defined, posing well‐known numerical challenges [1].

The Climate Modeling Alliance Atmosphere Dynamical Core: Concepts, Numerics, and Scaling

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract This paper presents the dynamical core of the Climate Modeling Alliance (CliMA) atmosphere model, designed for efficient simulation of a wide range of atmospheric flows across scales. The core uses the nonhydrostatic equations of motion for a deep atmosphere, discretized with a hybrid approach that combines a spectral element method (SEM) in ...

Patterns of Composition, Richness and Endemicity of Cyperaceae Across Open and Closed Habitats in Madagascar's Central Highlands

Biotropica, Volume 58, Issue 2, March 2026.
We assessed Cyperaceae species composition, richness and endemicity across closed (forest), dry open (dry grasslands, rocky outcrops, bare dry soils), and wet open (marshes, swamps, wet grasslands, riparian areas) habitats in Isalo National Park and the Itremo Massif Protected Area, both in Madagascar's Central Highlands.

Quasi‐Fuchsian flows and the coupled vortex equations

Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.
Abstract We provide an alternative construction of the quasi‐Fuchsian flows introduced by Ghys. Our approach is based on the coupled vortex equations that allows to see these flows as thermostats on the unit tangent bundle of the Blaschke metric, uniquely determined by a conformal class and a holomorphic quadratic differential.
