Image of the experimental setup with inset showing the IPMC-based wedge.
Schematic of the IPMC-based wedge impacting the free surface of a liquid with overlaid coordinate system and variables’ definition.
Snapshots of the wedge impacting the free surface with superimposed PIV data for the right hand side of the wedge. Time is indicated in the insets and H = 20 mm.
Deflection of the right IPMC at the 5 markers for t = 0, 7, 14, 24, and 39 ms (top) and time history of such deflections (bottom).
Short circuit current (dashed line) and tip displacement (solid line) versus time. Red, green, blue, and purple lines refer to H = 20, 40, 60, and 80 mm, respectively.
Peak short circuit current (top left); rise time of short circuit current (bottom left); peak tip deflection (top right); and rise time of tip deflection (bottom right) versus impact velocity.
