Figure 2 shows the averaged HRR during the combustion of various NH 3  and CH 4 -based fuels in the  engine cylinder at
Figure 4 shows experimental LBVs along with kinetic modelling predictions for NH 3 -based blends
Figure 6 shows the propagation of lean flames at u’=1.04m.s -1 . The turbulent-to-laminar velocity ratio  increases when the flame surface equivalent radius R s  increases, suggesting that combined turbulent  wrinkling  and  stretch  effects  influence  th
Figure  8a  shows  the  dependence  of  the  turbulent-to-laminar  velocity  ratio  on  the  effective  Lewis  number: increasing
