| Abstract: |
| To developed the numerical simulation technique of pulse detonation engine(PDE),the DET2D code was developed.By using the DET2D code,an whole engine computation has been rerformed for the NPS valveless PDE.The results show that the code is steady and efficient for multi-tube PDE and air breathing PDE.The results validate the principle of PDE operation and code. |
