| Research Abstract |
A small, pulse detonation combustor with a length of 20cm and a volume of 120cm^3 was developed for several kW-class micro gas turbines. As a method to increase the cycle frequency, the counterflow and parallel fuel injection methods were proposed, and the premixture flow behavior and concentration distribution were measured. By using the turbulent flame jet-type initiators, detonation was attained in a hydrogen-fueled combustor. The exhaust behavior of the burned gas was observed. To shorten the exhaust process, the increase of the air flow velocity was effective.
