水素供給パイプライン設備形成における流量と熱量に応じた管口径選定

抄録

In order to establish the design methodology of the hydrogen pipeline network, the design concept of the pipeline diameter was examined. Firstly, the flow experiments of hydrogen were conducted to verify the applicability of the general equation to calculate the relationship between flow rate and pressure loss in a pipe. By using the equation, the diameter of the hydrogen pipelines was determined under some virtual target conditions of flow rate or calorific value and was compared with that of typical city gas in Japan. As a result, it was suggested that the diameter of the hydrogen pipelines is equivalent to that of city gas in case of transporting the same calorific value
