Abstract
We present results from the simultaneous application of planar laser-induced uorescence (PLIF)
and particle image/tracking velocimetry, complemented by direct numerical simulations, aimed at
the detailed hydrodynamic characterization of harmonically excited liquid- lm ows falling under
the action of gravity. The experimental campaign comprises four di erent aqueous-glycerol solutions
corresponding to four Kapitza numbers (
Ka
= 14, 85, 350, 1800), spanning the Reynolds number
range
