چکیده انگلیسی
The laminar flame speeds for 2,4,4-trimethyl-1-pentene/air mixtures have been measured in a constant volume combustion bomb, at initial temperatures of 400 and 450â¯K, initial pressures of 0.1 and 0.3â¯MPa, and equivalence ratios from 0.6 to 1.5. Both the linear and nonlinear models are used for extrapolation of unstretched flame speed. It is observed that there is a small discrepancy in laminar flame speed using linear and nonlinear models at Ï⩽1.1, while this discrepancy becomes larger at higher equivalence ratio. Moreover, a chemical kinetic model for 2,4,4-trimethyl-1-pentene including 50 species and 361 elementary reactions is developed. Full validations show that the present model can well predict both ignition delay times and laminar flame speeds, at a wider range of initial temperatures, initial pressures and equivalence ratios. Using the present model, the rate of production analysis is performed to investigate the main reaction pathways of 2,4,4-trimethyl-1-pentene combustion. The analysis indicates that the differences of reaction pathways at high and low temperatures, are mainly embodied in the three aspects of primary reactions of 2,4,4-trimethyl-1-pentene, reactions of TC4H9, and reactions of isobutenyl.
