- 摘要：
- Laminar flame speeds of 2,4,4-trimethyl-1-pentene are investigated at equivalence ratios of 0.7–1.6, initial temperatures of 298–453 K and initial pressures of 0.1–0.5 MPa. The comparison between 2,4,4-trimethyl-1-pentene and iso-octane is also performed. Results show that 2,4,4-trimethyl-1-pentene has faster laminar flame speed than iso-octane. Chemical kinetic models (Metcalfe model, Modified model I) were tested against the present experimental data. The laminar flame speeds are apparently over-estimated by the Metcalfe model and under-predicted by the Modified model I. Therefore, high-level quantum mechanical calculations were used to revise the Modified model I to obtain Modified model II and it can give fairly good prediction at various conditions on laminar flame speeds. In addition, the chemical kinetic analysis was conducted. The analysis indicates both thermal and kinetic effects result in the discrepancy of laminar flame speeds between 2,4,4-trimethyl-1-pentene and iso-octane. Furthermore, IC4H8 plays a dominant role in laminar flame speeds of 2,4,4-trimethyl-1-pentene and iso-octane.
