| Research Abstract |
We carried out experiments using a cylindrical tube, whose inner diameter and length were respectively 16mm and 401mm, with a buffer chamber as the combustor. The combustor was operated at 100Hz in valveless mode. To evaluate the characteristics of the jet, we directly observed the jet and measured the history of the total pressure at 100mm from the exit. Although the jet lasted 2.5ms when no buffer chamber was installed, it lasted 10ms when a proper buffer chamber was installed, that is, a quasi-stationary jet was successfully obtained.
