Numerical investigation and optimization on laminar burning velocity of ammonia-based fuels based on GRI3.0 mechanism

Yulei Bao et al.

Summary: Ammonia is considered an ideal fuel for future clean energy, but its low combustion intensity limits its application. Mixing hydrogen and methane can effectively improve the combustion performance of ammonia fuel, with hydrogen having a more significant enhancement. This study identifies the most sensitive reaction related to combustion intensity and optimizes a new mechanism for predicting laminar burning velocity.
