Hydraulic characteristics of turbine impeller
Collection of Czechoslovak Chemical Communications, 1982The study concentrates on the determination of hydraulic characteristics (volumetric flow rate, power output, hydraulic efficiency and total head) of a standard, six-blade turbine impeller in a flat-bottomed cylindrical vessel provided with radial baffles at a turbulent regime of agitated liquid. The investigated characteristics are determined by means

A set of empirical equations has been developed which defines the peak efficiency and shape of the efficiency curve for hydraulic turbines as a function of the commissioning date for the unit, rated head, rated flow, runner speed, and runner throat or impulse turbine jet diameter.

Measurement of Hydraulic-Turbine Vibration
Journal of Fluids Engineering, 1952Abstract This paper describes a test program used to measure and eliminate the vibration which had produced extensive cracking in the blading of a slow-speed, 40,000-hp hydraulic turbine. Strains, accelerations, and pressures were measured at various locations on the turbine runner while the unit was in operation.

Cavitation in Hydraulic Turbines
1962The most common and troublesome maintenance problem encountered with hydraulic turbines is the erosion caused by cavitation. A study of the cavitation phenomenon has demonstrated that the pressure produced by the collapse of cavitation bubbles is sufficient to cause mechanical erosion of all known materials. However, the resistance to cavitation damage
