In this paper the turbulent flow in a cyclonic separator is investigated with large-eddy simulation (LES) based on a cylindrical coordinate spectral-element-Fourier method (SEM) using the Smagorinsky subgrid-scale model in its standard and dynamic formulation. The results show slight model differences, but both have poor agreement with measurements. The cylindrical-coordinate system geometry us...

As part of the Sloshing Wing Dynamics H2020 EU project, an experimental campaign was conducted to study slosh-induced damping in a vertically excited tank filled with liquid water or oil and air. In this work, we simulate these experiments using two numerical approaches. First, single-phase, weakly compressible model is used, gas flow (air) not modeled. For approach, proven Smoothed Particle Hy...

Successful adoption and implementation of ERP Systems has been the subject of extensive research as can be evidenced by the large body of research literature on this topic. However, the effect of cross-cultural issues has been less widely studied, perhaps because of the difficulty and complexity of such cross-cultural studies. In today’s global business environment this remains a key issue and ...

The modeling of fresh concrete flow is still very challenging. Nevertheless, it highest relevance to simulate these industrially important materials with sufficient accuracy. Often, assumed show a Bingham-behavior. In numerical simulations, regularization must be used prevent singularities. Two different models, namely the 1) Bi-viscous, and 2) Bingham-Papanastasiou are investigated. Those mode...

The context of this paper is the simulation parameter-dependent partial differential equations (PDEs). When aim to solve such PDEs for a large number parameter values, Reduced Basis Methods (RBM) are often used reduce computational costs classical high fidelity code based on Finite Element Method (FEM), Volume (FVM) or Spectral methods. efficient implementation most these RBM requires modify co...

In this paper the damage location in beam like-structure is determined using static and dynamic data obtained using finite volume method. The change of static and dynamic displacement due to damage is used to establish an indicator for determining the damage location. In order to assess the robustness of the proposed method for structural damage detection, three test examples including a static...

A finite-volume model has been developed to study incompressible forced flow heat transfer of air over a circular cylinder in cross flow. An artificial compressibility technique is applied to couple the continuity to the momentum equations. The proposed explicit finite-volume method (FVM) uses a novel discretization in time and space. The governing equations are solved by time-marching using a ...

Abstract In this study the isogeometric B-Rep mortar-based mapping method for geometry models stemming directly from Computer-Aided Design (CAD) is systematically augmented and applied to partitioned Fluid-Structure Interaction (FSI) simulations. Thus, newly proposed methodology geometries described by their Boundary Representation (B-Rep) in terms of trimmed multipatch Non-Uniform Rational B-S...

The Multi-Level Monte Carlo finite volumes (MLMC-FVM) algorithm was shown to be a robust and fast solver for uncertainty quantification in the solutions of multi-dimensional systems of stochastic conservation laws. A novel load balancing procedure is used to ensure scalability of the MLMC algorithm on massively parallel hardware. We describe this procedure together with other arising challenges...
