Determining the laminar burning velocity of nitrogen diluted dimethoxymethane (OME1) using the heat‐flux burner method: Numerical and experimental investigations

International Journal of Energy Research, Volume 45, Issue 2, Page 2824-2836, February 2021., 2021
In this work, the heat‐flux method is used to investigate the laminar burning velocity of the oxygenated fuel OME1/DMM. The fuel is experimentally and numerically compared to laminar burning velocity of propane, ethanol and other oxygenated fuels and the influence of temperature and nitrogen admixture is investigated. OMEs are in general more resistant
