Optimization of a Micromixer with Automatic Differentiation [PDF]
Fluids, 2022 As micromixers offer the cheap and simple mixing of fluids and suspensions, they have become a key device in microfluidics. Their mixing performance can be significantly increased by periodically varying the inlet pressure, which leads to a non-static ...

OpenLB—Open source lattice Boltzmann code
Computers and Mathematics With Applications, 2021 We present the OpenLB package, a C++ library providing a flexible framework for lattice Boltzmann simulations. The code is publicly available and published under GNU GPLv2, which allows for adaption and implementation of additional models. The extensibility benefits from a modular code structure achieved e.g. by utilizing template meta-programming. The

Fluid–Structure Interaction Simulation of a Coriolis Mass Flowmeter Using a Lattice Boltzmann Method
Fluids, 2021 In this paper, we use a fluid–structure interaction (FSI) approach to simulate a Coriolis mass flowmeter (CMF). The fluid dynamics is calculated by the open-source framework OpenLB, based on the lattice Boltzmann method (LBM). For the structural dynamics

Implicit propagation of directly addressed grids in lattice Boltzmann methods
Concurrency and Computation: Practice and Experience, Volume 35, Issue 8, 10 April 2023., 2023 Summary Lattice Boltzmann methods (LBM) are well suited to highly parallel computational fluid dynamics simulations due to their separability into a perfectly parallel collision step and a propagation step that only communicates within a local neighborhood.

Conjugate heat transfer through nano scale porous media to optimize vacuum insulation panels with lattice Boltzmann methods [PDF]
Computers and Mathematics with Applications, 2019 Due to reduced thermal conductivity, vacuum insulation panels (VIPs) provide significant thermal insulation performance. Our novel vacuum panels operate at reduced pressure and are filled with a powder of precipitated silicic acid to further hinder ...

Lattice-Boltzmann coupled models for advection–diffusion flow on a wide range of Péclet numbers [PDF]
Journal of Computational Science, 2021 Traditional Lattice-Boltzmann modelling of advection–diffusion flow is affected by numerical instability if the advective term becomes dominant over the diffusive (i.e., high-Péclet flow).

OpenLB-UQ: An Uncertainty Quantification Framework for Incompressible Fluid Flow Simulations
arXiv.orgUncertainty quantification (UQ) is crucial in computational fluid dynamics to assess the reliability and robustness of simulations, given the uncertainties in input parameters. OpenLB is an open-source lattice Boltzmann method library designed for efficient and extensible simulations of complex fluid dynamics on high-performance computers. In this work,
