In the present analysis, the cycle of pulse detonation engine (PDE) operation, such as combustion, exhaust and filling phases, was performed by 2-dimensional calculations. A 2nd-order MacCormack-TVD scheme is used to solve Navier-Stokes equations where a simplified two-step chemical reaction model is introduced. Model PDEs have various tube lengths with a constant cross section, containing an Ar-diluted stoichiometric oxyhydrogen mixture. The performance of PDE was estimated and compared with the result of Endo-Fujiwara theoretical analysis. In the present PDE performance estimation, useful formulas for impulse per unit area that are in good agreement with theoretical analysis are derived. Through the cycle analysis of PDE operation, the thrust density of each Model PDE was also estimated and essential aspects of the PDE cycle were obtained.
