“…However, it was found that the NO emission of the gas turbine increases significantly with increase of ammonia concentration. Okafor et al 23 investigated the flame speed properties of methane/ammonia blend both experimentally and numerically under different pressure and equivalence ratio conditions.…”

“…The analysis was conducted using RANS k-w SST modelling that is known to provide good average results for tangential swirling flows [46,47]. For the resolution of combustion, complex chemistry was employed by using a reduced kinetics mechanism developed by Okafor et al [27]. The model was resolved using clustering to accelerate the chemistry resolution.…”

“…Similarly, Glarborg et al [25] gathered a vast quantity of resources to develop an improved reaction mechanism, which is currently under evaluation by several research groups, showing accurate results for some equivalence ratios on the improvement of NNH reactions and NO formation [26]. Finally, works performed by Okafor et al [27], who used the GRI-Mech 3 [28] mechanism in combination with Tian's 16 reaction model, have also denoted good agreement with experiments. The model, developed by Tohoku's group, uses Tian's reactions for ammonia/hydrogen in combination with GRI-Mech 3 methane reactions.…”

“…However, there are also challenges with using NH 3 as fuel. The laminar flame velocity of NH 3 is about one-fifth that of hydrocarbons Xiao et al, 2017;Okafor et al, 2018Okafor et al, , 2019a. The adiabatic flame temperature of NH 3 is lower than that of hydrocarbons because the heating value (LHV) of NH 3 is about half that of hydrocarbons (NH 3 : 18.6 MJ/kg, CH 4 : 55.5 MJ/kg).…”
