Abstract: The current guidelines for sump design with respect to the transport of floating debris provides only information for a limited number of sump geometries. Basically, there is a need for a more generic formulation of guidelines with respect to the transport of (floating) debris. In the research for these new guidelines for transporting debris, free surface vortices are defined as an governing mechanism for the transport of floating debris. To achieve knowledge on the ability of vortices as transport mechanism and for the verification of CFD models, experiments in a real scale test facility will be conducted. The experiments must provide data on the influence of different types of floating debris on the formation of surface vortices, the transitions between vortices and the transport ability i. e. duration and stability of various types of vortices. An experimental set-up provides 2D visual data of the surface activity and behavior of floating debris. The set-up also provides data of pump performance measurement which is presumed to be influenced by air entrainment and pre-rotation.
