COM3D Code

COM3D is computational fluid dynamics (CFD) software suite dedicated for simulation of gas combustion and distribution in turbulent environment. This code is being developed at the Institute for Thermal Energy Technology and Safety (ITES) in the Karlsruhe Institute of Technology (KIT) since 1995 and is used in multiple application simulations and research studies.

The turbulent reactive flow code COM3D is intended to model development of large-scale combustions including explosions and detonations, transport, and mixing of hydrogen or other combustible gases in geometrically complex environment with multiple compartments and internal structures in a multi-block computational domain.


Among different applications of COM3D code, safety analysis for nuclear power plants was playing the primary role for last three decades…
