Measurement of non-steady forces in three turbine stage geometries using the hydraulic analogy
Abstract
A rotating model turbine stage consisting of a row of stationary inlet nozzles and a rotating blade row was used to analyze the nonsteady forces and torques acting at the center of gravity of an instrumented moving turbine blade. A flow of water was used to simulate two-dimensional gasdynamic flow through the three turbine stages. Results are presented for tangential, axial, and torsional directions in terms of a dimensionless force ratio, or torque ratio, respectively.
