GOVERNMENT/SCIENCE
APPLICATIONS
- Used in microgravity science
missions aboard the NASA KC-135 aircraft to measure flow characteristics:
- in R-134a refrigerant loop
by NASA GRC Microgravity Division
- in HFE-7000 refrigerant loops by Texas A&M University
- Basis for subsequent
development of sensor for packed bed reactors; complete packed beds
test facility delivered to NASA GRC in 2005
