Abstract
The sources of non-steady forces in a turbine stage are reviewed. Procedures for line-vortex stage flow analysis and for actuator disk analyses are described, with details of analytical contributions to these areas. Experimental procedures for measurements of blade non-steady forces in the laboratory and in the field are described. Selected test data are included. Recent developments using the rotating water table approach are reviewed.
