The detailed mechanisms of di-n-butyl ether(DBE)and n-octanol were reduced to obtain a skeletal mechanism for each fuel by using methods of the direct relation graph with error propagation and sensitivity analysis(DRGEPSA),and of isomer lumping and peak concentration analysis.The skeletal mechanisms of DBE and noctanol were then combined together to generate a final skeletal mechanism,in which 117 species and 601 reactions are included.The ignition delays of detailed mechanisms of DBE and n-octanol,the experimental data of laminar flame speeds of DBE,and the experimental data of species concentration in a jet stirred reactor(JSR)for noctanol were used to validate the skeletal mechanism.Finally,the reaction pathways of DBE and n-octanol at low and high temperatures were analyzed.The results show that the skeletal mechanism can well predict the ignition delay time,laminar flame speed and the species concentration in the JSR.
