The utilization of H 2 blended natural gas has great significance for advancing large-scale applications of hydrogen energy. Numerical simulation can provide valuable insights into the combustion characteristics of H 2 blended natural gas. To calculate the radiative characteristics of H 2 O/CO 2 mixed gas under complex conditions efficiently and accurately in CFD simulation, new multi-parametrical pressurized WSGG correlations were proposed in this study, which introduced a set of parameters that can simultaneously adapt to variations in temperature, pressure and H 2 O/CO 2 molar ratio. The model coefficients are applicable across a wide range of conditions, including a total pressure range of 1∼10 bar, a temperature range of 400∼2500 K, H 2 O/CO 2 molar ratio from 3–5 and partial pressure path lengths from 0.001 to 60 bar·m. The new correlations were validated under one- and two-dimensional cases. The average error of radiative heat flux was less than 3.92% and the average error of radiative heat source was less than 4.32%, while traditional WSGG models developed under standard pressure failed to comprehensively meet the demands. The calculation results indicated that the new multi-parametrical pressurized WSGG correlations can effectively simulate radiative calculations in combustion media under varying pressures and are suitable for the fuel with high H 2 blending ratios, which is significant for hydrogen energy utilization. • New radiation model is designed for H 2 blended natural gas combustion in 1∼10 bar. • Multi-parameters of temperature, pressure and molar ratio are compatible with the model. • Proposed model shows great agreement with benchmark in radiation transfer cases. • Comparison between the proposed and previous WSGG models is conducted. • Detailed parameters and fitting methods are given.
