초록
Numerical simulations of freely propagating flames burning methyl decanoate(MD)/air mixture are performed under the condition of initial temperature 650 K and pressure 1~10 atm in order to understand the pressure effect. The revised chemical kinetic mechanism is used, which involves 118 species and 1,674 forward reactions. The calculations about the flame speeds at high pressure and the mole fraction of species at atmospheric pressure are compared with those obtained from the experiments performed by other researcher, the results of which are in good agreement. The flame structure of a premixed methyl decanoate/air flame has a tendency similar to that of hydrocarbon fuel. Decomposition of methyl decanoate occurs mainly through reactions with hydrogen atoms. At high temperature the unimolecular reaction, MD→C3H5O2 + C8H17, plays an important role to decompose methyl decanoate. Increasing the pressure leads to an increase in the net production rate of carbon dioxide.
