Characteristics of wind Power Systems

• For a given wind speed, rotor efficiency is a function of the rate at which the rotor turns. A common way to illustrate rotor efficiency is to present it as a function of the tipspeedratio: where rpm is the rotor speed, D is the rotor diameter (m) and v is the wind speed (m/s) upwind of the turbine.

VMA Introduction to the milling technology with the bead

It does not matter whether the power input which leads to the existing energy density, is applied with a high speed and low torque or vice versa. With a given bead charge and dispersion time, the dispersion result depends only on the amount of the mechanical power. The torque therefore depends directly on the flow characteristics of the millbase.
