Finite Element Modelling to Predict the Fire Performance of Bio-Inspired 3D-Printed Concrete Wall Panels Exposed to Realistic Fire

open access: yesBuildings, 2022
Large-scale additive manufacturing (AM), also known as 3D concrete printing, is becoming well-recognized and, therefore, has gained intensive research attention.

Numerical analysis on influence of surface structures of cathode catalyst layers on performance of polymer electrolyte fuel cells

open access: yesElectrochemical Science Advances, 2023
Because it is time‐consuming to optimize the design of a cathode catalyst layer (CCL), a numerical simulation to predict the reaction and mass transport characteristics without trial and error is desirable.

Rubber Impact on 3D Textile Composites [PDF]

open access: yes, 2011
A low velocity impact study of aircraft tire rubber on 3D textile-reinforced composite plates was performed experimentally and numerically. In contrast to regular unidirectional composite laminates, no delaminations occur in such a 3D textile composite ...

A comparative study for the performance of encased granular columns

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2019
This paper describes a three-dimensional (3D) numerical analysis of a test embankment on geotextile-encased columns (GECs), in comparison with two-dimensional (2D) axisymmetric and plane strain analyses.

A Note on Analysis and Numerics for Radiative MHD in 3D [PDF]

open access: yesPAMM, 2003
AbstractThe equations of radiative magnetohydrodynamics describe the dynamics of an electrically conducting fluid interacting with magnetic fields and radiation. In particular they provide a widely accepted mathematical model for the physics in the solar photosphere and convection zone. In the spatially three‐dimensional case we present several notions

Direct numerical simulation of turbulence at lower costs [PDF]

open access: yes, 1995
Direct Numerical Simulation (DNS) is the most accurate, but also the most expensive, way of computing turbulent flow. To cut the costs of DNS we consider a family of second-order, explicit one-leg time-integration methods and look for the method with the

3D Numerical Simulation and Performance Analysis of CO2 Vortex Tubes

open access: yesApplied Sciences, 2021
In view of the extensive application of swirl flow pipes (vortex tubes) in refrigeration systems, the parameters of swirl flow pipes were investigated to provide optimal cooling and heating conditions. Three-dimensional numerical simulations were carried
