Optional Powerpoint file
ACCOMPLISHMENTS
    • Demonstrated the feasibility of non-intrusive measurement of temperature and density in a flowing gas stream
    • Developed an optical measurement technique for use in compressor flow fields
COMMERCIALIZATION
    • $11K Phase III funding for further development of the temperature measurement system at Glenn’s compressor test facility
    • A new approach for non-intrusive measurement of gas temperature based on an O2-LIF technique has been  demonstrated at GRC as a result of the Phase III funding
    • GRC may use additional Phase III funds for demonstration tests in a compressor after reviewing results in the final report
GOVERNMENT/SCIENCE APPLICATIONS
    • This technique will be used in the “Smart Green Engine” Program
    • Will be used in the NASA Physics and Process Modeling Program (PPM)
    • Useful in turbomachinery research over a temperature range of 300K-500K
    • Useful in research applications requiring non-intrusive measurement of gas temperature
