It is well known that a large dense intruder may rise to the surface of a vibrated, granular bed the Brazil nut effect.? In this paper we describe a water-enhanced Brazil nut effect which occurs when the vibrated granular bed is fully immersed. In a liquid. We use a bed of glass beads immersed in water and monitor the behaviour of a large steel intruder as the system. Is vibrated vertically. To aid our understanding we have, developed numerical simulations to model this system and provide. Detailed information on the fluid and grain motion. The mechanism responsible for the rapid rise of the intruder is shown. To be fluid-enhanced ratcheting rather than simple differential drag.
