Development of BIM‐Based Tunnel Information Modeling Prototype for Tunnel Design

Advances in Civil Engineering, Год журнала: 2024, Номер 2024(1)

Опубликована: Янв. 1, 2024

Designing and modeling tunnels are a complex labor‐intensive process, exacerbated by the involvement of multiple designers software applications to accommodate diverse geometric subsurface conditions. This often results in reduced efficiency, productivity, increased potential for errors. To address these challenges, authors implemented strategy integrating building information mathematical relationships governing tunnel geometries rock support elements. Using Autodesk Revit, they developed prototype that allows model aligned with ground conditions without reliance on applications. streamlined approach enhances simplifies complexities, improves accuracy design review processes, including quantity take‐offs. A case study comparing conventional methods demonstrated significant improvements accuracy. research offers practical benefits stakeholders projects, optimizing work quality, outcomes construction.

Effect of External Electric Field on Fluidization of Rod-Like Particles Using Cfd-Dem

Опубликована: Янв. 1, 2024

Due to the significant effect of an external electric field on hydrodynamics a fluidized bed and importance using rod-like particles in practical applications, behavior containing presence different fields is studied. Simulations were performed coupled computational fluid dynamics-discrete element method (CFD-DEM), generated multisphere approach with aid quaternions. The vertical horizontal orientation was investigated. Also, particle size their constant explored this work. results showed that increasing strength reducing lead increment tendency become oriented along direction field. Moreover, at various inlet gas velocities probability distribution porosity This study provides deeper understanding fluidization field, its can be utilized design optimize relevant processes.
