Turbulence and Heat Transfer in Porous Layers

Published:Dec 29, 2025 23:09
1 min read
ArXiv

Analysis

This paper investigates the complex interaction between turbulent vortices and porous materials, specifically focusing on how this interaction affects turbulence kinetic energy distribution and heat transfer. The study uses direct numerical simulations (DNS) to analyze the impact of varying porosity on these phenomena. The findings are relevant to understanding and optimizing heat transfer in porous coatings and inserts.

Breathing Coefficient for Porous Body Swelling

Published:Dec 29, 2025 08:32
1 min read
ArXiv

Analysis

This paper introduces the 'breathing coefficient' as a tool to analyze volume changes in porous materials, specifically focusing on how volume variations are distributed between solid and void spaces. The application to 2D disc packing swelling provides a concrete example and suggests potential methods for minimizing material expansion. The uncertainty analysis adds rigor to the methodology.
Reference

“The analytical model reveals the presence of minimisation points of the breathing coefficient dependent on the initial granular organisation, showing possible ways to minimise the breathing of a granular material.”

Differentiable Inverse Modeling with Physics-Constrained Latent Diffusion for Subsurface Parameter Fields

Published:Dec 27, 2025 01:01
1 min read
ArXiv

Analysis

This paper introduces a novel method, LD-DIM, for solving inverse problems in subsurface modeling. It leverages latent diffusion models and differentiable numerical solvers to reconstruct heterogeneous parameter fields, improving numerical stability and accuracy compared to existing methods like PINNs and VAEs. The focus on a low-dimensional latent space and adjoint-based gradients is key to its performance.
Reference

“LD-DIM achieves consistently improved numerical stability and reconstruction accuracy of both parameter fields and corresponding PDE solutions compared with physics-informed neural networks (PINNs) and physics-embedded variational autoencoder (VAE) baselines, while maintaining sharp discontinuities and reducing sensitivity to initialization.”

Multiscale Filtration with Nanoconfined Phase Behavior

Published:Dec 26, 2025 11:24
1 min read
ArXiv

Analysis

This paper addresses the challenge of simulating fluid flow in complex porous media by integrating nanoscale phenomena (capillary condensation) into a Pore Network Modeling framework. The use of Density Functional Theory (DFT) to model capillary condensation and its impact on permeability is a key contribution. The study's focus on the influence of pore geometry and thermodynamic conditions on permeability provides valuable insights for upscaling techniques.
Reference

“The resulting permeability is strongly dependent on the geometry of porous space, including pore size distribution, sample size, and the particular structure of the sample, along with thermodynamic conditions and processes, specifically, pressure growth or reduction.”
