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.
~ 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
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.
