Cavitation of Hydraulic-Turbine Runners
Journal of Fluids Engineering, 1940Abstract This paper contains a brief analytical discussion of runner cavitation. The I. P. Morris cavitation equipment is described, and results with this apparatus are compared with those of the Holtwood laboratory. A calibration gage in the development stage is also described.

Submergence Factors for Hydraulic Turbines
Journal of Energy Engineering, 1989The elevation of a hydroelectric turbine above or below tailwater is based on hydraulic model studies to determine the critical sigma, defined as the ratio of barometric pressure plus submergence depth at which cavitation commences divided by the rated head.

Index Testing of Hydraulic Turbines
Journal of Fluids Engineering, 1951Abstract The object of this paper is (a) to bring to the attention of operating companies the benefits derived from index tests of hydraulic turbines, and especially those of the adjustable-blade propeller or Kaplan type; (b) to enumerate and discuss the presently known methods of determining relative discharge and hence relative ...
