We are happy to announce that we will extend our cooperation with Frantisek Prinz, Frantisek Lizal and many more from the Brno University of Technology. In March we first published a paper on paper on Comprehensive experimental and numerical validation of Lattice Boltzmann fluid flow and particle simulations in a child respiratory tract. Now we aim to study particle transport and deposition within the human respiratory system. This is essential for understanding various physiological and pathological processes as well as for developing effective drug delivery strategies. While considerable research has focused on male airway models, there is a growing recognition of the need to investigate female-specific airway geometries due to significant anatomical and physiological differences between sexes.

We are honored to welcome Yongbo Deng from Institute of Microstructure Technology (IMT)

Yongbo Deng is visiting us for a presentation on Topology Optimization of Micro and Nano Structures, which introduces a theoretical method for the development of Highly lightweight structures. This technique has numerous applications, metalenses in visible and infrared light, metalens arrays and many more.

We sincerely thank Yongbo Deng for his time and effort and look forward to future collaborations!

At the Institute of Mechanical Process Engineering and Mechanics (MVM) and the Institute of Applied and Numerical Mathematics (IANM) at the Karlsruhe Institute of Technology (KIT) we are looking for a Research assistant for our team Lattice Boltzmann Research Group (www.lbrg.kit.edu). Within the scope of a research project on the modelling and simulation of turbulent multi-component fluid flows, a full-time position is to be filled temporarily.

Besides enjoying scientific problem analysis as well as mathematical and/or process/chemical/mechanical engineering problems and/or computer science using parallel computers (CPU and GPU cluster), we expect you to have good programming skills, initiative, imagination and good communication skills in written and spoken German and English. Great importance is attached to working in a team.

Please send applications with the usual documents, preferably electronically in a pdf file, to mathias.krause@kit.edu

The SeaDream project strengthens EU efforts to achieve climate neutrality and to meet green energy and environmental targets.

SeaDream plays a crucial role in ensuring that marine energy is used sustainably and that coastal environments are preserved in line with EU policies.

The development of a high-resolution water-quality data service at sea is at the core of SeaDream’s mission. Data like these are crucial for addressing specific questions regarding maritime renewable energy generation and storage. In cooperation with the University of Luxembourg, the University of Liverpool, and several other partners, the Lattice Boltzmann Research Group (LBRT) at KIT will work on this project for four years.

Registration is now open for the 8th Spring School 2025 on Lattice Boltzmann Methods with OpenLB and ProLB Software Lab that will be held in Marseille/France form 19.05.2025 – 23.05.2025.

The spring school introduces scientists and applicants from industry to the theory of LBM and trains them on practical problems. The first half of the week is dedicated to the theoretical fundamentals of LBM up to ongoing research on selected topics. Followed by mentored training on case studies using OpenLB or ProLB in the second half, where the participants gain deep insights into LBM and its applications. This educational concept is probably unique in the LBM community and offers a comprehensive and personal guided approach to LBM. Participants also benefit from the knowledge exchange during poster session, coffee breaks and the excursion. We look forward to your participation.

We are honored to welcome Philipp Spelten from the University of Siegen at the Lattice Boltzmann Research Group (LBRG) at KIT.

During his visit, Philipp worked on aeroacoustics and noise prediction for airfoils with Lattice Boltzmann Simulations in OpenLB.We would like to thank Philipp for his time and effort. We are looking forward to future collaborations.

We are excited to announce the publication on “Benchmark Simulation of Laminar Reactive Micromixing Using Lattice Boltzmann Methods” in the American Institute of Aeronautics and Astronautics Journal. There, we reestablish a benchmark for a reactive laminar micromixer using lattice Boltzmann methods (LBM) with special treatment of specie transport in secondary vortices resolved till the smallest Batchelor scale. This research was done with help of the open source CFD software OpenLB.

The article is published in the AIAA Journal under subscription: https://doi.org/10.2514/1.J064234 and is freely available as preprint at https://dx.doi.org/10.13140/RG.2.2.10086.64326

We are excited to announce the publication on “Calculation of Single and Multiple Low Reynolds Number Free Jets with a Lattice-Boltzmann Method” in the American Institute of Aeronautics and Astronautics Journal. In this research, we investigated behavior of a free jet and free jets bundle at distinct Reynolds numbers using lattice Boltzmann method and OpenLB. The article is published in the AIAA Journal under subscription: https://doi.org/10.2514/1.J064280

From October 6-11, 2024, the LBRG successfully organized the first OpenLB Hackathon in Feldberg, Germany. For one week, 14 group members focused on core development to further improve OpenLB in terms of boundary condition modeling, GPU support and user friendliness.

We have just released a new video on our OpenLB YouTube Channel:.
