Heat Transfer in Unfrozen and Frozen Porous Media: Experimental Measurement and Pore‐Scale Modeling

Water Resources Research, Volume 56, Issue 9, September 2020., 2020
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

, 2023
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,

Binary fluid flow simulations with free energy lattice Boltzmann methods [PDF]

, 2023
We use free energy lattice Boltzmann methods to simulate shear and extensional flows of a binary fluid in two and three dimensions. To this end, two classical configurations are digitally twinned, namely a parallel-band device for binary shear flow and a

JAX‐LaB: A High‐Performance, Differentiable Lattice Boltzmann Library for Modeling Multiphase Fluid Dynamics in Geosciences and Engineering

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract We introduce JAX‐LaB, a differentiable, Python‐based Lattice Boltzmann simulation library designed for modeling multiphase and multiphysics fluid dynamics problems in hydrologic, geologic, and engineered porous media settings. The library is designed as an extension to XLB (Ataei & Salehipour, 2024, https://doi.org/10.1016/j.cpc.2024.109187 ...

Simulating Stirred Tank Reactor Characteristics with a Lattice Boltzmann CFD Code

Chemical Engineering &Technology, Volume 47, Issue 3, Page 586-595, March 2024.
There is a need for reliable models of mixing in stirred tanks, which is widely used in the chemical and process industry but complex and not fully understood. A lattice Boltzmann code with a large eddy simulation turbulence model was used to determine power numbers and mixing times in stirred tanks with different impellers.
