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

open access: yesProceedings 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 ...

Global Graph Surrogates and Neural Graph Elements for Computational Mechanics

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Machine learning surrogates are increasingly used to accelerate physics‐based simulations by predicting full‐field responses at a fraction of the computational cost. In this contribution, we present two complementary graph‐based approaches for surrogate modelling in computational mechanics.

On the Coupling of Reaction–Diffusion–Transport Equations With Biot's Poroelasticity Model: An Application to Meniscus Regeneration

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Regenerative medicine is a promising approach for the treatment of meniscus injuries. In silico experiments provide a valuable framework for optimizing such therapies by improving the understanding of both environmental effects on cell behavior and the interaction between cells and nonwoven scaffolds, which act as porous media supporting cell ...

A Coupled FE‐FFT Multiscale Framework for Heterogeneous Porous Materials Using preCICE

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT This work presents a coupled finite element–fast Fourier transform (FE–FFT) multiscale framework for the simulation of heterogeneous and graded porous materials. The macroscopic boundary value problem is solved with the finite element (FE) method in Julia using Ferrite.jl, while the microscopic response of periodic unit cells is obtained from ...
