Sloshing Lab

Sloshing Lab is an INSEAN reserach laboratory, built to perform dedicated experimental activities on the sloshing flows in a LNG ship tank and water entry and exit of 2D ship sections.

The lab consists of three different facilities:

  1. a single degree of freedom mechanical system, designed and  built at the INSEAN workshop. It is used to impose a pure-sway sinusoidal motion to a 2D and 3D prismatic sloshing tank. The amplitude of the oscillatory motion can vary from 3 cm to 10 cm, while its frequency from 0.1 Hz to 1.5 Hz. The mechanism is designed to perform PIV measurements in a reference system fixed to the moving tank.    
  2. a six degree of freedom mechanical system 'Hexapod' for sloshing experiments of 2D and 3D tanks. Built by Symetrie (www.symetrie.fr), the Mistral II platform can support a maximum payload of 1 ton.  The maximum amplitude of motion is 47 cm for the translational dofs and 45 deg for the rotational ones. The maximum frequency of the oscillatory motion is about 2 Hz (with a maximum amplitude of 4 cm and 4 deg). The platform has been designed to perform PIV measurements in a reference system fixed to the moving tank. 
  3. a 2D Water-entry and exit facility. Built and designed at INSEAN, it is used for the experimental research activity on water-entry/exit of 2D ship-like sections. The maximum water depth is 1.2 m and the velocity of the body at the instant of the impact can vary between 0.3 m/s and 4 m/s.
