Abstract

This project aims at studying gravity-capillary wave turbulence between two immiscible fluids in a vertical cylindrical tank. When two-layers fluid systems are disturbed or sheared, gravity, viscosity and capillarity act to restore the interface. It is planned to measure the wave height at the interface between both flowing fluids. It is anticipated that the modulation of the angular velocity of the inner cylinder and the fluids heights will significantly influence the gravity and capillary wave turbulence regimes. The waves properties and morphologies as well as their breakup will be monitored. It will serve as a test case for multiphase flow problems.
