Mini Review of Spherically Expanding Premixed Turbulent Ammonia Flames

Abstract

Ammonia is recognized as a potential hydrogen carrier but increasingly as a carbon free fuel for all energy applications. However, significant challenges exist in ammonia combustion due to its low flammability, low burning intensity and the potential for high detrimental emissions. This mini review article focuses on the state of the art in understanding the specifics of turbulence-flame interaction of partially cracked and uncracked ammonia in the expanding spherical flame configuration. The paper highlights the need for experimental data coupled with DNS to develop useful modeling tools that accurately predict the specific response of the ammonia flame to the turbulence front.
