The characterization of the flowfield of a dump combustor
… flowfield, a water-cooled, stainless steel dump combustor model was developed. A two-component Laser Doppler Anemometer (LOA) was used to measure the mean and turbulent velocities in the axial and tangential directions and provide a comparison between combusting and isothermal flows. …

Investigation of liquid fuel jet injection into a simulated subsonic "dump" combustor
… designed to represent a sudden-expansion "dump" combustor were performed under cold-flow conditions. Test conditions were as follows: 0.6 entrance Mach number, 25 PSIA total pressure, and nominally 75°F stagnation temperature. Two step heights were investigated, 1.0 in. and 0.5 in., …

A new method for calculating the flow field in a dump combustor
… procedure for solving the flow field in a dump combustor is described. The elliptic calculation is used at the dump combustor entrance and a parabolic calculation downstream. The calculations are restricted to steady axisymmetric nonreactive incompressible flow. A great savings in …

Modelling of turbulent stratified flames
… flames, a turbulent stratified V-flame and a dump combustor fed by two streams of different mixture strength. This work highlights the importance of this quantity and its influence on the simulation results. Any model for stratified combustion requires at least two variables to describe the …

experimental investigation of a reacting transverse jet in a high pressure oscillating vitiated crossflow
Staged combustion is one design approach in a gas turbine engine to reduce pollutant emission levels. In axially staged combustion, portions of the air and fuel are injected downstream of a lean premixed low NOx primary combustion zone. The gas residence time at elevated temperatures is decreased …
