Pilot Scale Tests Alden/Concepts NREC Turbine

PDF Version Also Available for Download.

Description

Alden Research Laboratory, Inc. has completed pilot scale testing of the new Alden/Concepts NREC turbine that was designed to minimize fish injury at hydropower projects. The test program was part of the U.S. Department of Energy's Advanced Hydropower Turbine Systems Program. The prototype turbine operating point was 1,000 cfs at 80ft head and 100 rpm. The turbine was design to: (1) limit peripheral runner speed; (2) have a high minimum pressure; (3) limit pressure change rates; (4) limit the maximum flow shear; (5) minimize the number and total length of leading blade edges; (6) maximize the distance between the runner ... continued below
