Abstract (Summary)

This thesis investigates the ability of numerical simulations to analyze the ignition process of liquid oxygen (LOX) / liquid methane (LCt4). Experimental data from a NASA glow plug ignition system is used for validation. The ignition process is simulated numerically by solving the Reynolds Averaged Navier-Stokes (RANS) equations with combustion.

Successful ignition requires sufficient enthalpy and adequate equivalence ratio. The calculated region of equivalence ratio required to achieve successful ignition is identified and compared with experimental data. Numerical predictions agree with experimental data between a ratio of 0.31 and 0.42. At higher equivalence ratios, some disagreements exist, likely due to differences in geometry between tests and simulations. The numerical results indicate that, for the simulated configuration, successful ignition is achieved in the 0.31 and 0.90 equivalence ratio range.
