Numerical simulation of the process on a pulse detonation engine;

Detonation phenomena, detonation physics, detonation propulsion concepts and their research are introduced with a special emphasis on topics of interests, such as pulse detonation engines, oblique detonation wave-based ramjet and scramjet, ram accelerators.

In order to investigate the variable characteristics of the shock wave external flow field of pulse detonation engine(PDE),by use of two-dimensional viscous space-time conservation element and solution element(CE/SE)method,the mathematical and discrete grid model was derived.

Numerical investigation of multi-tube pulse detonation engine with common nozzle;

Exprimental investigation of integrating pulse detonation engine system;

Experimental investigation of air-breathing valveless pulse detonation engine;

Numerical simulation of the flow field of multicycle pulse detonation engine(PDE) is helpful for understanding the engine principle and performance analysis,and can provide the useful information for PDE design.

To improve the reliability of pressure measurement in detonation combustor of pulse detonation engine(PDE),the pressure/time curves of detonation were measured at single detonation and multicycle detonation,respectively,by using a dynamic pressure measurement system.

The results show that all nozzles can augment the thrust of baseline pulse detonation engine(PDE)and there is an optimal nozzle area ratio where thrust augmentation is maximized.

A new device system was developed to measure the pulsed temperature and vapor concen- tration in the exhaust flow during the multicycle process of pulsed detonation engine.
