HIGHLIGHTS
- What: The results of this study have important engineering significance for the safe transportation of hydrogen-blended natural gas transportation systems. Only the distribution of gas concentration in the direction of gravity at the outlet was considered. In this paper, the influence of the undulation angle, undulation height, pipeline diameter of the undulation pipeline as well as the ball valve opening, inlet pressure, temperature, velocity, hydrogen blending ratio and other parameters on the distribution of hydrogen concentration in the pipeline are calculated and analyzed by using the CFD method.
- Who: Weiqing Xu and colleagues from . . .
