Thermal anemometry for mass flow measurement in oscillating cryogenic gas flows.

Summary

Constant temperature anemometers and resistance temperature detectors have been adapted to measure the instantaneous mass flow rates and temperatures in oscillating gas flows at frequencies up to 30 hertz and temperatures down to 70 K. These devices were used to study the behaviour of the oscillating working fluid (helium) in a regenerative refrigerator called an orifice pulse tube refrigerator with little intrusion in the system. Calibration procedures are presented. Under these conditions the sensors appear to have an uncertainty of less than 1.6%.
