The qualification of Computational Fluid Dynamics (CFD) codes for two-phase flows is an important topic in the frame of German CFD initiative initiated by the Gesellschaft für Anlagen- und Reaktorsicherheit (GRS). This concerted action especially aims on phenomena in the primary system of light water reactors. The Transient twO Phase FLOW (TOPFLOW) test facility is one of the reference experimental facilities within this CFD network. One type of experiments aims on generation of CFD-grade data (i.e. data with high resolution in space and time) for poly-dispersed bubbly flows. Such data were obtained at the TOPFLOW facility for upwards vertical pipe flow using the wire-mesh sensor technique. Different experimental series were done for adiabatic air-water and steam-water flows as well as for condensing and evaporating flows. Beside bubbly flows the database also comprises measurements for slug, churn-turbulent and wispy-annular flows. The aim of this presentation is to give an overview on the available database.
