N2 - Aim: The introduction of the full paper reviews Refs.3 through 6, points out what we believe to be their shortcomings, and then, proposes what we believe to be a better method of numerical simulation, which is explained in sections 1 and 2. Their core consists of: (1) a finite-rate chemistry CFD (computational fluid dynamics) model and second order upwind scheme were used in the 2-D simulation of gaseous mixture of propane and air detonation; (2) the spark ignition model in CFD software was used to simulate the spark plug ignition used in experiments. Section 3 is entitled numerical simulation results and their analysis; Figs. 2 through 6 present the simulation results; the analysis of these results shows preliminarily that, compared with the results of CEA(Chemical Equilibrium and Applications)calculation code, the errors of C-J values were less than 4%, thus proving that the methods of mesh generation and calculation used in this paper can indeed be used in the simulation of multi-cycle detonation initiated by small energy ignition.
