Hydraulic Model Studies of the Intake-Outlet Structure for the Pump-Generation Facility at Mormon Flat Dam, Salt River Project, Arizona
Hydraulic model studies were made to determine flow characteristics in the upper intake-outlet structure of the Mormon Flat Dam pump-generation facility in Arizona. Of particular concern were the velocity distribution and turbulence conditions at the trashrack location during the pumping cycle. The studies showed how the flow was not evenly dispersed in the initial structure having 20.5 deg diverging sidewalls and parallel floor and roof. Auxiliary piers and horizontal and vertical deflectors were related to velocity distribution. Three additional intake-outlet structures with lesser sidewall divergence were studied. Ultimately selected was a structure with 13 deg 10 min diverging sidewalls and 5 deg divergence in the floor and roof. Primarily for structural reasons, the structure included one pier at the penstock end and three piers at the reservoir end. Flow distribution was considered adequate. Head losses in the structure were from 0.6 to 0.77 of a velocity head during the pumping cycle, and about 0.19 of a velocity head during the generation cycle.
