Determine autoignition delays as a function of the initial reactor temperature,Ti, pressure, p, and equivalence ratio, Q, for CH4-air combustion. Please consider three initial temperatures (1100 K, 1300 K, and 1500 K), two pressure levels (1 atm and 10 atm), and four equivalence ratios (0.3, 0.5, 1.0, and 1.5). This results in a total of 24 possible combinations for (Ti, p, Q). Please use tables and/or plots for comparative analysis. For the case with T = 1500 K, p = 1 atm, Q = 0.5, plot the temperature and species concentrations of some important radicals leading up to the ignition point. Please also explain how you determined the autoignition delay time in your results.
