Abstract: Flip buckets have been widely used in release works due to its simple structure and economics. For purpose of enhancing energy dissipation and avoiding flow choking, the dentate flip buckets with an offset are developed in this paper. The model tests results indicated that, the gap at the dentate flip bucket center separates the flow into two branches. Correspondingly, the flow regimes of the jets include overlapping jets transition jets and separating jets. The aerator at the gap may protect the dentate buckets from cavitation damage due to air entrainment. Comparing with the traditional flip buckets, the energy dissipation is improved about 15% for the dentate flip buckets. Base on the analysis of the influencing factors on the energy dissipation rate, the expression of the energy dissipation for the dentate flip buckets is provided in this paper
