In this study, one-dimensional detailed simulations of stretched premixed counterflow flames are conducted to investigate the flame extinction, bifurcations, and burning limits of NH3/air and NH3/H2/air mixtures at elevated pressures up to 25 atm. For the NH3/air mixtures, the incorporation of radia...
