ABSTRACT Latent heat energy storage systems (LHESS) using phase change materials (PCMs) offer high thermal energy storage density and effective temperature regulation due to their ability to absorb and release heat at nearly constant temperatures. However, accurately simulating the melting process of PCMs remains challenging due to the nonlinear nature

OpenLB User Guide: Associated with Release 1.6 of the Code
OpenLB is an object-oriented implementation of LBM. It is the first implementation of a generic platform for LBM programming, which is shared with the open source community (GPLv2). Since the first release in 2007, the code has been continuously improved and extended which is documented by thirteen releases as well as the corresponding release notes ...

Implicit propagation of directly addressed grids in lattice Boltzmann methods
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.

A single‐phase CFD model with a lattice Boltzmann method of an innovative 3D‐printed wet‐scrubber nozzle is implemented to analyze and optimize its pressure drop. The numerical model is validated against experimental data. An optimization approach regarding the flow guidance and pressure drop of the nozzle as well as the impact on the product ...

2D simulation and analysis of fluid flow between two sinusoidal parallel plates using lattice Bolzmann method [PDF]
In order to obtain a better heat transfer, it is important to enhance fluid mixing in heat exchangers. Since there are negative effects when heat exchangers are operating in turbulent regime (like significant pressure drop, increased size of the pump)

Heat Transfer in Unfrozen and Frozen Porous Media: Experimental Measurement and Pore‐Scale Modeling
Abstract In this work, we conducted a mechanistic study on pore‐scale mechanisms controlling heat transfer in partially saturated porous media at unfrozen and frozen conditions. Experimental measurement of effective thermal conductivity (ETC) of simulated partially saturated sediments was carried out to explore the effect of different parameters ...

Research Software Engineering in OpenLB: Refactoring a Legacy Code to State-Of-The-Art Performance
Lattice Boltzmann Methods (LBM) are an established approach for simulating a wide variety of transport phenomena. The software framework OpenLB has been in continuous development for 15 years and counting as one of the major open source LBM research codes. Due to the need to develop the library alongside the primary research of the involved scientists,

THE OPENLB PROJECT: AN OPEN SOURCE AND OBJECT ORIENTED IMPLEMENTATION OF LATTICE BOLTZMANN METHODS
The OpenLB project aims at setting up an open source implementation of lattice Boltzmann methods in an object oriented framework. The code, which is written in C ++, is intended to be used both by application programmers and by developers who may add their own particular dynamics.
