| Abstract: | In this study, the confined explosion characteristics of ethyl acetate were investigated in a constant volume explosion vessel using the initial pressure of 1–4 bar, the initial temperature of 358–418 K, and the equivalence ratio of 0.8–1.4. It was revealed that the peak explosion pressure and the maximum pressure rise rate of ethyl acetate increased as the initial pressure increased and the initial temperature decreased. The peak explosion pressure and maximum pressure rise rate were obtained at the equivalence ratio of 1.2 due to increased heat release rate. Furthermore, the explosion time decreased as the initial pressure decreased. In summation, EA experimental and theoretical deflagration index were investigated and compared. The experimental deflagration index showed that EA explosion was less dangerous, whereas the theoretical deflagration predicted that the explosion could be more hazardous. |
