Homogenizers for Mixing, Dispersing, and Emulsifying
Rotor-stator homogenizers (also called colloid mills or Willems homogenizers) generally outperform cutting blade-type blenders and are well suited for plant and animal tissue. Combined with glass beads, the rotor-stator homogenizer has been successfully used to disrupt microorganisms.
Characteristics of wind Power Systems - UNLV
• → Maximum theoretical rotor efficiency = 59.3% • Modern wind turbine blades can approach 80 percent of the above limit, i.e., 45% - 50% efficiency in converting the power in the wind into the power of a rotating generator shaft. • For a given wind speed, rotor efficiency is a function of the rate at which the rotor turns.

OPTIMAL ROTOR TIP SPEED RATIO
A rotor that rotates slowly will allow the wind to pass unperturbed through the gaps between the blades. A rotor rotating rapidly will appear as a solid wall to the wind. It is necessary in the design of wind turbines to match the angular velocity of the rotor to the wind speed in order to obtain maximum or optimal rotor efficiency.

generator. In this type of generator, direct current from a separate source is passed through windings on the rotor by means of slip rings and brushes. This maintains a rotating electromagnetic field of fixed polarity (similar to a rotating bar magnet). The rotating magnetic field of the rotor extends outward and cuts through the armature
How a Wind Turbine Works - Text Version | Department of Energy
How a Wind Turbine Works. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates ...

The blades of the rotor are forced to rotate due to the air flow. The rotor shaft meshes with the generator, and consequently, the rotor shaft rotation leads to electricity generation. This type of turbine is usually designed to ensure that the rotor blades are facing the wind, thus it utilizes wind sensor and servo motor.

However, the modern rotor blade can go beyond the barrier method. When the wind forces the blades to move, it will transfer some of its energy to the rotor. Most turbines come with two or three blades. Shaft. The shaft is connected to the center of the wind-turbine rotor. When the rotor spins, then the shaft also turns with its flow.
