Abstract In flow velocity measurements, resolution, miniaturization, and accuracy of measuring devices are important issues because the measuring devices significantly affect the flow in the micro-space, sonic flow, and turbulent flow. We studied rec

Critical-flow Venturi nozzles (CFVNs) are used widely as transfer standards and can measure flow rates accurately. However, previous research has reported that in some CFVNs, the pressure-recovery effect of the diffuser is poor, and it is called the

The calibration facility with the multi-nozzle calibrator was developed for the calibration of flow meters to be used with high-pressure, high-flow-rate hydrogen gas. The critical nozzles installed in the multi-nozzle calibrator were calibrated with

Recovery Temperature Anemometry (RTA) was used to investigate flow fields in critical flow nozzles without perturbing the flows. In RTA, the recovery temperature in the flow field is measured by using a very thin thermocouple wire, and the measured t

The critical nozzle flow meter was developed for high-pressure hydrogen gas flow measurements, and its characteristics was experimentally examined with hydrogen gas at the pressure up to 70 MPa. The results show that the critical back pressure ratio
