📄 Abstract（原文）
Hydrogen blending in natural gas pipelines is a promising decarbonization pathway. This study investigates a coaxial-swirl static mixer for hydrogen-natural gas mixing at ratios of 5% to 30% H₂. The mixer features nine ring-shaped cavities with 120° helical torsion to enhance turbulent mixing. A calibrated 2D axisymmetric computational model was developed and validated against experimental data. Results show that the configuration achieves 95% mixing uniformity within 8.2D to 9.0D across all blending ratios, meeting industry targets with minimal pressure penalty (<0.04% of operating pressure). Validation shows good agreement with literature, with mixing intensity profiles matching within 5%. This work supports the integration of hydrogen into existing infrastructure for near-term decarbonization.
