Resumen:
This work discloses similarity properties of a
high-aspect-ratio pulsating jet with lateral confinement
exhibiting axis switching in a region close to the jet exit.
The analysis is conducted separately within the major and
minor planes of the jet source. The similarity relations
derived from the in-plane flow equations are combined
with experimental data collected in a recent three-dimensional
velocimetry study of a glottal-like jet. Empirically,
non-collapsing profiles are shown to rescale as collapsing
profiles in the similarity variables within ranges of the
streamwise coordinate, which are determined by the analysis.
The similarity properties are shown to be useful to
make predictions on the jet axis-switching characteristics.
