The partial dissociation of the Ammonia molecule appears as a potentially interesting strategy not only to enhance Ammonia's combustion properties but also to guarantee flexibility for power production. Using the spherical expanding flame configuration, laminar burning velocities, Markstein lengths and turbulent flame speeds were measured for cracking ratios ranging from 10 to 40%, and 3 equivalence ratios of 0.8, 1.0 and 1.2. It was observed that lean mixtures exhibit the greatest increase in turbulent to laminar velocity ratio given the same turbulent intensity. This is was potentially due to opposite stretch related behaviour as well as preferential diffusional instability effects. Measurements presented herein correlate well with a Lewis Number weighted turbulent flame speed scaling law.
