Abstract Fluid energy mills are used because of their advantages in fine grinding The materials fed into a jet stream are accelerated to a relatively high velocity from 10 to 200 m/s and although these values are much higher than those encountered in the breeding process of crystals there are some similarities between these two operations.

This incremental damage mechanism is inherently less inefficient but leads to size reduction from the many weak collisions experienced by particles within the mill Finally size reduction from abrasion is well represented by the shear energy absorption of the particles.

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 both lift and drag.
