Research output: Contribution to conferencePaperpeer-review


A small-scale laboratory burner has been set-up to operate under driven pressure oscillating conditions. Pressure oscillations are created by oscillating the volume of the combustion chamber using a piston assembly. The oscillation amplitude to mean ratios of the volume and pressure range from 7 to 10 percent. Pressure, volume, and temperature are measured during a test. Speed (frequency) versus time is also tracked for the duration of the test. Preliminary results show some interesting phenomena, including a mean pressure that decreases with increasing frequency. The rate of change of speed also has an effect on mean pressure. The decrease in mean pressure is enhanced during periods of increasing frequency, and depreciated during periods of decreasing frequency. This suggests non-linear combustion behavior.
