Measurement of Pressure Pulsations in Francis Turbines
, 2010 The work presented in this thesis involves preparation and execution of measurements on Francis runners. The measurements were performed by means of onboard measuring equipment both in model runners and full-scale prototype runners. Also, analysis of the measured data, and the discussion of the results, is presented.

On Pulsation of Delivery Pressure of Gear Pump
Transactions of the Japan Society of Mechanical Engineers, 1956 The author derives theoretically the general equation for the pulsation factor of the delivery pressure of a gear pump and also describes his experiment to record the wave of the pulsating delivery pressure. It is thus found that the number of the delivery pressure pulsation per each revolution is always equal to that of the gear-teeth of the gear ...
