This video shows a simulation of the blow-out behavior of a premixed ammonia/hydrogen/nitrogen-air flame. Ammonia is a promising energy carrier that could eliminate CO2 emissions from gas turbine engines, but the combustion properties of pure ammonia are not well suited to gas turbine combustion. When ammonia is blended with hydrogen and nitrogen, however, the mixture exhibits more favorable combustion characteristics. The first view in the video shows a photorealistic rendering of the flame and air, which then transitions to show the temperature isosurface of the flame (1500 K) colored by velocity magnitude. The final view shows a slice with temperature contours and the mesh. As the velocity of the inflow increases, the flame blows out.
