This movie shows the flow behavior around a hydrofoil. A negative pressure generated over the hydrofoil causes large deformation of the free surface and the entrainment phenomena. The shear flow behind the hydrofoil induces instability similar to the Kelvin–Helmholtz instability and results in liquid bubble formation
Vibrations of the shell, which corresponds to the fuselage of a small pasenger airplaine, with “smeared” stiffeners; both the stringers and frames are “smeared.”

Flow visualization in the water supply tank: water supply and drain pipes are at one end of the tank, a circular baffle plate is installed in front of the outlet pipe and a diverging nozzle is installed in the inlet pipe.
