Intended for modeling
three dimensional reacting and nonreacting flow of gases in
complex Cartesian and cylindrical geometries. Typical systems modeled
include gas-fired utility boilers, waste incinerators and pyrolysis
furnaces. A particular emphasis is placed on pollutant formation and
destruction.

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 (manifold methods) and radiation calculations (discrete-ordinates)
can include any number of chemical species.
