Abstract

This study investigated the reaction characteristics in a pulse detonation engine, including pressure, temperature, compression ratio, sonic velocity, and detonation velocity, using CEC code and STAR-CD. The former was used for the calculation of equilibrium states, whereas the latter was used for the simulation of reaction dynamics. A complete pulse detonation tube and measurement system were designed for these experiments with monitoring and recording performed using Lab VIEW. The ignition energy as well as detonation pressure and temperature were studied experimentally and the results were compared with numerical predictions. Our results provide useful insight into the design and performance of pulse detonation engines.
