Experimental study of splashing mechanisms by an immersed rotating body

ORAL

Abstract

We study the entrainment of water by a rotating wheel, as a function of the rotation frequency, wheel radius and depth of immersion. The entrainment leads to the formation of a liquid sheet on the ascending side, and of ligaments on the descending side. These structures are captured via simple models. We measure via image processing the liquid flux ejected by the wheel.
