Coupling 3-D Radiation, Reaction and CFD

Intended for modeling three dimensional reacting and nonreacting 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.

CAPABILITIES:
~ 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

APPLICATIONS:
~ burner and furnace design ~ chemical process heaters ~ reboilers ~ flares ~ waste incineration ~ pollutant formation and destruction ~ SNCR ~ radiation in participating media ~ computational fluid dynamics ~

ALGORITHMS: robust, accurate, iterative solvers to extract the non-linear coupling between turbulent fluid mechanics, gas phase reaction chemistry (including NOx) and 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.
