Low-frequency pressure oscillation is discovered in the jet wake region.
- class="label">•
Low-frequency oscillation is proved to be generated by turbulent jet vortex.
- class="label">•
Affected width of low-frequency oscillation is found to be similar as turbulent jet width.

Angular coefficient of half width (ranging 0.2268–0.2887) reduces with water temperature.
