About the Lattice Boltzmann Research Group (LBRG)

The Lattice Boltzmann Research Group (LBRG) headed by Dr. Mathias J. Krause is an interdisciplinary research group at the Karlsruhe Institute of Technology (KIT). It was founded in 2013 as an initiative of the KIT Institutes for Applied and Numerical Mathematics 2 (IANM2) and for Mechanical Process Engineering and Mechanics (MVM) aiming at taking advantage of novel mathematical modelling strategies and numerical methods to enable large-scale simulations as well as optimal control of fluid flows for applications in the field of process engineering. With the highly fruitful multidisciplinary environment provided by the two institutes as well as with the exorbitant engagement of all their researchers, the LBRG became a world-wide recognised and leading group for Lattice Boltzmann Methods (LBM).

The team of LBRG consists of mathematicians, engineers and computer scientists. We face challenges for a better fundamental understanding of suspensions in general as well as for the improvement of mechanical processes and medical treatments. In particular we design and use models, algorithms and open source simulation tools such as OpenLB, always taking advantage of modern high performance computers for the simulation of e.g.

  • Particulate fluid flows
  • Thermal flows
  • Turbulent flows
  • Material transport and chemical reactive flows
  • Light transport
  • Fluid-structure interaction
  • Flows in porous media and complex geometries

Our teaching and education concept is project- and research-oriented. For our students we offer for example basic programming courses, lectures on parallel computing, software tutorials and advanced seminars on particular fluid flow simulations as well as optimal control theory. The students also participate in current research projects as student assistants supervised by PhD students. Annually, an open spring school on LBM with an OpenLB software lab is offered to newcomers from around the world.

The LBRG cooperates with private companies and research groups from all around the world, e.g. from Brazil, Tunisia, China, France, UK, USA and many more. On the one hand, this gives students the chance for research internships abroad. On the other hand, research on LBM and engineering applications in general is accelerated, which benefits from the common open-minded exchange and development of the OpenLB software.
