Numerical investigation on air-fuel configurations on the emission features in a vortex flameless combustion at various thermal intensity

A numerical study on the effects of air/fuel configuration on NOx emissions control using methane fuel combustion at different thermal intensity was conducted in this paper. The investigation employed the structure of small combustors which are influenced by some combustion factors. The layout is pr...
