- 摘要：
- Ignition delay times were measured for cyclohexane, ethylcyclohexane, and n-propylcyclohexane at atmospheric pressure, equivalence ratios of 0.5, 1.0, and 2.0 and temperatures of 1110 – 1650 K behind reflected shock waves with fixed fuel concentration of 0.5%. Computational simulations were made using three generally accepted mechanisms, yielding acceptable agreements with the current measurements at the tested equivalence ratios. Nonetheless, there is a slight over-prediction at phi = 2.0 for n-propylcychexane. Ethylcyclohexane and n-propylcyclohexane have shorter ignition delay times than cyclohexane at high temperature. However, this difference decreases with the decrease in temperature. Simulation and comparison with previous data indicate that the oxidation rates of ethylcyclohexane, n-propylcyclohexane, and n-butylcyclohexane are in the order of n-propylcyclohexane > ethylcyclohexane ≈ n-butylcyclohexane. Kinetic analysis is performed to obtain insight into the observation.
