摘要

Ignition delay times for n-decane/O2/Ar mixtures were measured behind reflected shock waves using endwall pressure and CH* emission measurements in a heated shock tube.The initial postshock conditions cover pressures of 0.09-0.26 MPa,temperatures of 1 227-1 536 K,and oxygen mole fractions of 3.9%-20.7% with an equivalence ratio of 1.0.The correlation formula of ignition delay dependence on pressure,temperature,and oxygen mole fraction was obtained.The current data are in good agreement with available low-pressure experimental data,and they are then compared with the prediction of a kinetic mechanism.The current measurements extend the kinetic modeling targets for the n-decane combustion at low pressures.
