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.

Key words: Pulse detonation engine;Numerical simulation;2D(Two-dimensional)

摘要： 为了获得脉冲爆震发动机(PDE)工作过程数值模拟技术,发展了DET2D程序,并以美国海军研究生院的气动阀式PDE为研究对象,进行了整机数值模拟。结果显示:所发展程序稳定、高效,可以用于多脉冲PDE流场的数值模拟及吸气式PDE数值模拟。通过计算,验证了PDE的工作原理和所发展程序的正确性。
