- 摘要：
- Ignition delay times of ethylcyclohexane with a fixed fuel concentration of 0.5% were measured behind reflected shock wave at pressures of 1.1 – 10.0 atm, equivalence ratios of 0.5 – 2.0 and temperatures between 1000 and 1700 K. The measured ignition delay times were compared with predictions by the mechanism JetSurF2.0 29 and fairly good agreements were presented under the test conditions. The ignition delay time of fuel-rich mixture was suggested to overwhelm that of fuel-lean mixture when tested at low temperature, elevated pressure. Analysis was conducted to kinetically interpret the effects of pressure, temperature, equivalence ratio and fuel-concentration on the time-histories of OH radical and intermediate species of hydrocarbons. Results showed that the suppression of reaction H+O2 <=> OH+O by fuel-concerned radicals played an important role. Sensitivity analyses were carried out to provide an insight into the controlling reactions on the ignition of ethylcyclohexane.
