Coupling 3-D Radiation, Reaction, and CFD

BANFF is intended for modeling three dimensional reacting and non-reacting flow of gases in geometries. Typical systems modeled include gas-fired utility boilers, waste incinerators and flares. A particular emphasis is placed on pollutant formation and destruction.


  • Complex three-dimensional geometries
  • Steady state, laminar or turbulent flows with/without relaminarization
  • Mixing and reaction of multiple fuels
  • Full coupling between turbulent fluid mechanics, radiative and convective heat transfer, and chemical reactions
  • Radiative heat transfer for absorbing-emitting, turbulent, sooting media
  • NOx/SOx formation and destruction
  • Variable thermal boundary conditions including adiabatic, thermal resistance, “heat exchanger”
  • Soot


  • Burner and furnace design
  • Chemical process heaters
  • Reboilers
  • Flares
  • Waste incineration
  • Pollutant formation and destruction
  • SNCR
  • Radiation in participating media
  • Computational fluid dynamics


  • Robust, accurate, iterative solvers to extract the non-linear coupling between turbulent fluid mechanics
  • Gas phase reaction chemistry (including NOx)
  • Heat transfer (particularly radiation)
  • Turbulent fluctuations are accounted for by computing statistical distributions for reaction and radiation properties with several different mixing models (prescribed pdf, eddy dissipation concept)
  • Reaction and radiation calculations (discrete-ordinates) can include any number of chemical species
