Rotation

The rotation of the platform is ensured by 23 steel wheels, 10 having a motorization and 13 supporting the 300T load. Rotation periods range between 20s and 1000s, with a stability of 1e-4.

With the rotation, the free surface of waters curves down, ensuring equilibrium between centrigugal and pressure forces ; once in solid body rotation, the Coriolis Force effects can be studied independently, the effect of centrigugal forces resulting simply in a tilt of gravity.

The setup of solid body rotation is called the "spin-up" and is by itself the object of active research on turbulent boundary layers flows.
