Methane ignition delay
Web24 jul. 2024 · The ignition delay times measured in the HPST were defined as the time between the arrival of the reflected shock wave and the steepest pressure increase due to the ignition. Figure 1 depicts a typical pressure–time history and the determination of the ignition delay time in a shock tube experiment.
