Abstract
We developed the critical nozzle flow meter used at high-pressure and high-flow-rate hydrogen gas for the practical application of fuel cell vehicles and their infrastructure. This paper describes the results of characteristic evaluation of the flow meter in high Reynolds number area for nitrogen gas. The results show that the critical back pressure ratio is 0.92-0.93 and its discharge coefficient decreases with increasing the Reynolds number. These results are similar to the results for hydrogen gas qualitatively.
