Jodie Gail Pope (Fed)
Dr. Jodie Pope is a mechanical engineer specializing in hydrocarbon liquid flow and transient gas flow metrology in the Sensor Science Division at the National Institute of Standards and Technology.
Pope joined NIST in 2011 to study how the calibration of turbine flow meters depends on the properties of the fluid being metered. One result of this research was to replace hazardous hydrocarbon liquids then used to calibrate turbine flow meters at NIST (and elsewhere) with benign, surrogate liquids. A second result was to increase the accuracy of flow measurements made when a turbine meter is calibrated with one fluid at one temperature and then used to measure the flow of another fluid at another temperature.
Pope’s research evolved to include measuring rapidly changing gas flows such as those encountered when vehicles are refueled with compressed natural gas or high-pressure hydrogen gas. Pope went onto develop a transportable system that can test the accuracy of gaseous fuel dispensers in the field. Pope’s current research involves measuring high pressure (> 7 MPa) gas flow using the technique of acoustic gas thermometry in a large (1.85 m³), unthermostated collection tank. Dr. Pope also serves as a technical assessor for the National Voluntary Laboratory Accreditation Program (NVLAP).
