ABSTRACT

This paper reports the results of an experimental study to determine the effects of interaction between two cylinders of a pulse detonation engine as well as to estimate the thermal efficiency of the system with a turbine. An interaction between the tubes occurs if a diffracted shock wave propagates into the other tube, which disturbs its filling process. The system is able to be operated in 40 Hz per tube, which means 80 Hz in total. The thermal efficiency of this system was estimated by measuring work done by a compressor, driven by the turbine. It is concluded that for designing a multi-cylinder system, it is important to consider the interference between the tubes and the nozzle.
