The fitting coefficients of ngWSGG-PS and the codes for calculating the parameters of ngWSGG-PS

Description

This data provides the MATLAB code to calculate the absorption coefficients, weight factors, wall emissivities and wall absorptivities of ngWSGG-PS at given thermodynamic state. The data is applicable to conditions with nongray wall, pressures of 1-50 atm, temperatures of 300-2800 K, H₂O/CO₂ molar ratios of 0.05-4, and soot volume fractions of 0-20 ppm.

Steps to reproduce

The supplementary material contains a directory and nine MATLAB code files. The directory includes fitting coefficient files for the absorption coefficient, weight factor, wall emissivity, and wall absorptivity. The files read_coefficient_of_absorption_coefficient.m, read_coefficient_of_weight_factor.m, read_coefficient_of_emissivity.m, and read_coefficient_of_absorptivity.m are codes for reading the fitting coefficients of the absorption coefficient, weight factor, emissivity, and absorptivity, respectively. The files calculate_absorption_coefficient.m, calculate_weight_factor.m, calculate_emissivity.m, and calculate_absorptivity.m are codes for computing the fitted formulas of the absorption coefficient, weight factor, emissivity, and absorptivity, respectively. The file calculate_parameters_for_specific_thermodynamic_state.m is the code for calculating the absorption coefficient, weight factor, wall emissivity, and wall absorptivity at a given thermodynamic state. It should be noted that the wall emissivity and wall absorptivity can be refitted according to the selected wall material, without requiring any changes to the codes related to the absorption coefficient and weight factor.
