Simulation of Non-Premixed Natural Gas Flame

A numerical study to model a non-premixed natural gas flame in a 300 kW gas turbine combustor was undertaken by solving the appropriate form of governing equations in an axi-symmetric, two-dimensional domain. The numerical simulations are performed using RNG k- for turbulent transport along with a suitable radiation model for various wall conditions. The results are then compared with measured data for mean flow field temperature and species concentrations. The comparison of computed results with experimental data is found plausible.
