Experiment Data Report for DTT Rake Test in the FAST Facility

摘要

The results from testing the drag disc turbine transducer (DTT) rake in the Full Area Steady-State Test ((FAST) facility are reported and discussed. The velocity profiles measured by the traversing turbine probe inserted vertically and horizontally 2.3 diameters upstream of the DTT rake showed a lower velocity at the center portion of the pipe. However, the integrated volumetric flow rate with nominal transducer sensitivity provided by the manufacturer is only 8% higher than that measured by the reference full-flow turbine transducer. The approximate volumetric flow rate indicated by the DTT rake turbine transducers is at least 30% lower than the reference value without a rake blockage correction. The rake blockage correction increased the error to as much as 44%. (ERA citation 04:046602)
