Karlsruhe Institute of Technology (KIT) is developing the parallel computational fluid dynamics code GASFLOW-MPI as a best-estimate tool for predicting transport, mixing, and combustion of hydrogen and other gases in nuclear reactor containments and other facility buildings. GASFLOW-MPI is a finite-volume code based on proven computational fluid dynamics methodology that solves the compressible Navier-Stokes equations for three-dimensional volumes in Cartesian or cylindrical coordinates.

Low-emission hydrogen is expected to play an important role in the energy transition to tackle the climate crisis. It can decarbonate “hard-to-abate” sectors still relying on fossil fuels, turn low-carbon electricity into a fuel that can be transported using pipelines and provide a green transport alternative, in particular for heavy-duty and long-distance transport.
