Sentence examples for velocity oscillation from inspiring English sources

The results show that in gas combustion, the pressure, heat release rate and streamwise velocity oscillate with the same frequency but different phases, and that the inlet velocity oscillation periodically generates a large vortex near the dump plane that drives combustion instability.

Newly discovered is a short-wavelength, relatively large-amplitude transverse velocity oscillation on the jet axis.

This body mode helically twists the inner 20%-25 20%-25e jet, and the transverse velocity oscillation occurs at the fastest spatially growing wavelength predicted by the theory.

However, unlike the harmonic velocity oscillation, the combustion mode transition is hysteretic.

The effect of the unstable body modes on jet structure is analyzed for the first time, and a helical internal body mode is revealed to be responsible for the observed short-wavelength velocity oscillation on the jet axis.

Upstream excitation was provided by a loudspeaker producing velocity oscillation amplitudes of about 8% of the mean flow velocity.

These quasi-periodic velocity oscillations arise from a helical mode instability of the breakdown flow.

The velocity oscillations of the cylindrical casings were clearly captured in the experiments and analyzed theoretically.

Results of an experimental study of the effects of free-stream velocity oscillations of various amplitudes and frequencies are presented.

The velocity oscillations imposed by the acoustic wave mode are not the cause of instability because the velocity profiles atx≤150 mm do not resemble a Stokes shear wave.

Phase conditioned analysis of the flame dynamics yield additional criteria in highly responsive modes to include the effective amplitude of velocity oscillations induced by the acoustic pulsing.
