Abstract
The response behavior of capillary tube attenuated pressure sensor arrangements is studied using a rotating detonation engine as a nonlinear pressure wave source. The resulting measured pressures are examined as a function of the magnitude of the nonlinear pressure fluctuations, the mean pressure, and the forcing frequency applied to the pressure input port of the sensor. In addition, length and inner diameter of the sensor tubes are studied as a way to tie the current work into the established body of literature. Analytic models are used to provide understanding and predict the expected behaviors of the various tested sensor configurations, in an effort to supply reliable and accurate measurements of high-fidelity static pressures with specific application to ongoing rotating detonation engine research.
