Fuel (CH4) is injected into ports of a high velocity gas burner
located near the centerline. Air is supplied through the outer ports,
with secondary air delivered into an outer annular region. Directly
downstream of the annulus is a wedge-shaped annular baffle. The
mixing of fuel and air occurs downstream of this baffle and recirculation
zones behind the baffle provide stability and an attachment point
for the flame in the main combustion chamber. Combustion is assumed
to proceed via a two-step reaction mechanism, with turbulent mixing
as the limiting rate, as described by the Magnessen model.

Results
In the table below, a rating
listed in red corresponds to the redzone result, and one in bold is a peak
result. Bold red is used to
indicate that the run was both the peak and redzone result.
Results are listed alphabetically by platform, within each FLUENT version.
