Abstract:

	The accurate prediction of flow, species concentration, and temperature is essential
to the characterization and design optimization of combustors. To this end, it is
essential to include the effects of non-gray radiation and finite-rate chemical kinetics
in combustion modelling. This project addresses novel and highly parallel techniques
for this purpose. The discrete transfer model is used for non-gray radiation. For
stiff kinetics, a point-wise solution technique using stiff solvers for ordinary
differential equations is utilized. The Phase I effort will evaluate these techniques
within the framework of our commercial code FLUENT; verification problems from the
literature will serve to establish the correctness of results obtained. Phase II
would extend the implementation to non-orthogonal grids in our code FLUENT/BFC. At
culmination, this work would provide a comprehensive tool for the modelling of turbulent,
reacting subsonic flow and heat transfer in complex combustor geometries.

Potential Commercial Application:

Potential Commercial Applications: Enhanced capabilities for our current code, FLUENT,
which is presently being applied by industrial clients to model combustion applications,
will find reception in the gas turbine and the chemical vapor deposition communities.
