A coupled lattice Boltzmann/finite volume method for turbulent gas-liquid bubbly flows

Lauwers, Daniel; Meinke, Matthias; Schröder, Wolfgang (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] A simulation method for large eddy simulations (LES) of dispersed gas-liquid bubbly flows based on an Eulerian-Eulerian (E-E) model is presented. A volume averaging approach is used resulting in a set of conservation ...
Finite Element Simulation and Comparison of Piezoelectric Vibration-Based Energy Harvesters with Advanced Electric Circuits

Hegendörfer, Andreas; Mergheim, Julia (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] A system simulation method based on the Finite-Element Method (FEM) is applied to simulate a bimorph piezoelectric vibration-based energy harvester (PVEH) with different electric circuits: The standard circuit, the ...
An overview of p-refined Multilevel quasi-Monte Carlo Applied to the Geotechnical Slope Stability Problem

Blondeel, Philippe; Robbe, Pieterjan; François, Stijn; Lombaert, Geert; Vandewalle, Stefan (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] Problems in civil engineering are often characterized by significant uncertainty in their material parameters. Sampling methods are a straightforward manner to account for this uncertainty, which is typically modeled ...
Momentum conserving dynamic variational approach for the modeling of fiber-bending stiffness in fiber-reinforced composites

Kalaimani, Iniyan; Dietzsch, Julian; Groß, Michael (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] Rotor-dynamical systems made of 3D-fiber-reinforced composites which are subjected to dynamical loads exhibit an increased fiber bending stiffness in numerical simulations. We propose a numerical modeling approach of ...
Multilevel matrix-free preconditioner to solve linear systems associated with a the time-dependent SPN equations

Carreño, Amanda; Vidal-Ferràndiz, Antoni; Ginestar, Damián; Verdú, Gumersindo (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] The evolution of the neutronic power inside of a nuclear reactor core can be approximated by means of the diffusive time-dependent simplified spherical harmonics equations (SPN). For the spatial discretization of ...
