Spin Hall effect of vortex beams
Abstract
The existing 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 this 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. This work will validate nitrogen dilution using true low pressure testing compared to dilution in the same configuration, and further extend WSR capabilities by operating at elevated pressures up to 20 atm.
