Abstract
After several years of negative experience using conventional commercial water dynamometers directly driven at free power turbine speed, the author's company undertook an in-house design of a noncavitating dynamometer with the objectives of long life and low maintenance cost. The paper is a review of the design and performance of the dynamometer, utilizing smooth disk and stator elements and employing viscous shear variable immersion torque control.
