Vortical structure behind a circular disk was investigated experimentally in water as the flow past the disk was accelerated from rest and successively moved at constant speeds. Initial vortex ring growth and its distortion through subsequent vortex shedding were documented. Flow field was monitored until the steady state wake oscillation was established. The velocity time traces in the wake taken with a LDV were analyzed using a wavelet analysis technique, and time scales of vortical structures were identified and correlated with the flow visualizations.
