Summary: Green recyclability, high-energy density, and zero-carbon nature are the key advantages of magnesium sustainable fuel. This study evaluates two crucial issues related to premixed magnesium combustion, namely the trajectories of magnesium and magnesia, and pulsation flame. By considering detailed multi-zone flame structure and various factors, the governing equations and boundary conditions are derived. The results show that the importance of considered factors increases with decreasing particle diameter, and the heat loss of the combustion chamber has the greatest impact on flame velocity prediction.
