Element potential approach and its application to calculation of characteristic parameters of detonation wave

Using element potential approach, the characteristic parameters such as post-detonation pressure, post-detonation temperature and detonation wave velocity of pulse detonation engines with 6 conventional detonable fuels were calculated and reasonable variations of these parameters with excess air coefficient were obtained. Moreover, the conclusion was drawn that the higher fuel density was, the better the performance of PDE. Compared with our experimental results and those of corresponding calculation abroad, it is shown that the element potential approach is highly efficient and reliable in PDE research.
