Abstract

Highlights: * A piston mode of free surface motion is observed in the gap between the ellipsoid and lock gate; * The piston motion of free surface in the lock would significantly affect the force on the moving body. A negative wave-making resistance was observed when the ellipsoid was very close the lock gate.
