Intended for modeling
three dimensional reacting and nonreacting two-phase flow of gases
and particles or droplets in
complex Cartesian geometries. Typical applications
include coal-fired utility boilers, metallugical processing furnaces, rotary kilns,
and decoking process heaters.
Particular emphasis is placed on combustion and gasification
of pulverized coal and 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),
heat transfer (particularly radiation), particle phase reaction,
turbulent particle dispersion, and particle-wall or heat transfer
surface interactions.
Particle/fluid interphase coupling is included
through a moving-Eulerian particle cloud tracking and source distribution
technique. Computations of turbulent fluctuations include
statistical distributions for all reaction and
radiation properties. Reaction and radiation calculations can include
any number of chemical species.
