The well stirred reactor is a laboratory idealization of a gas turbine combustor that utilizes pre-mixed, pre-vaporized fuel and air flow to isolate chemical kinetic effects from the fluid dynamic effects. Data collected from a WSR can be applied to the design of modern gas turbine combustors by improving the accuracy and fidelity of combustion models. Of specific interest in the design of combustion systems is lean blowout. An existing well stirred reactor (WSR) has been successfully used to evaluate pollutant emissions, soot formation, combustion stability and alternative fuel performance at atmospheric pressure. The HPWSR project extends the capabilities of the current, atmospheric laboratory tool, allowing the generation of benchmark quality data over a range of operating pressures. Lean blow out data collected is correlated against loading parameter, forming fuel stability loops. Combustion stability of JP-8 will be evaluated over a range of operating pressures from 4 psia to 5 atm. A new, internal vaporization technique is applied to allow operation at higher pressures than with previous hardware. Lean emissions will be collected simultaneously and used to further characterize the HPWSR operability and lean combustion performance.
