Resumen:

In order to perform numerical simulations of the combustion of these blends with a reasonable CPU time, in recent literature, n-decane is generally chosen to represent diesel fuel. Also, as biodiesel components are even more complex, essentially composed of methyl esters, methyl-decanoate can be used to represent biofuels. Ethanol has a simple formula and is a widely-studied biofuel. The present work focuses on numerical studies of the combustion of n-decane/methyl-decanoate/ethanol blends. This study needs therefore a detailed chemical scheme describing the combustion of all the species included in the blend. In a recent work, we have developed a detailed chemical scheme by combining detailed schemes individually describing the combustion of diesel-ethanol blends and biodiesel blends respectively. This is done by carefully combining two chemical schemes, one originally for the combustion of diesel/ethanol due to Andrae  (150 species and 758 reactions), and the other for the combustion of biodiesel due to Luo et al. (115species and 460 reactions).
