Modeling and Simulation of Hydraulic Wind Turbine

Applied Mechanics and Materials, 2012
The wind energy can be transferred through an intermediate medium such as hydraulic fluids. In this paper a hydraulic system is utilized to transfer the wind energy from a wind turbine to a synchronous generator. A close loop hydraulic transfer system with fixed displacement pump and variable displacement motor is introduced and the mathematical model ...

Hydraulic Turbine Contra-Angle Handpiece

The Journal of the American Dental Association, 1953
A high rotary speed enhances the effi­ ciency of instruments used for cutting teeth in operative procedures. The small diameters of the dental cutting tools make it necessary to turn the instru­ ments at high rates of speed in order to obtain effective linear speeds for the re­ moval of enamel.

Hydraulic characteristics of turbine impeller

Collection of Czechoslovak Chemical Communications, 1982
The 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

Hydraulic turbine efficiency

Canadian Journal of Civil Engineering, 2001
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.
