A Numerical Investigation of the Flame Characteristics of a CH<sub>4</sub>/NH<sub>3</sub> Blend Under Different Swirl Intensity and Diffusion Models

A Numerical Investigation of the Flame Characteristics of a CH<sub>4</sub>/NH<sub>3</sub> Blend Under Different Swirl Intensity and Diffusion Models

This study investigates the effects of diffusion modeling and swirl intensity on flow fields and NO emissions in CH<sub>4</sub>/NH<sub>3</sub> non-premixed swirling flames using large eddy simulations (LESs). Simulations are performed for a 50/50 ammonia–methane blend at thre...
