Flow regime and energy dissipation of SFS-type flip buckets

In the present work, a slot-type flip bucket with separated flows, called SFS-type flip bucket, is developed, and flow regime and energy dissipation are experimentally investigated. Comparing with the circular-shaped or slot-type flip bucket buckets, the present SFS-type flip bucket has better flow regime and larger energy dissipation since the three branches of the flows are separated through the outlet of the flip bucket. Meanwhile, the energy dissipation for this flip bucket is estimated.
