BETZ Meaning and
Definition
-
Betz is a term commonly used in the field of wind energy to refer to the maximum amount of kinetic energy that can be captured by a wind turbine. It is derived from the name of the German physicist Albert Betz, who introduced the concept in the early 20th century. Betz's law, also known as the Betz limit or Betz coefficient, establishes a theoretical limit to the efficiency of a wind turbine.
According to Betz's law, the maximum possible extraction of kinetic energy from the wind is 59.3%. This means that no wind turbine can convert more than 59.3% of the available wind power into mechanical energy. The remaining energy is lost as turbulence and backflow.
The Betz limit takes into account the fact that when a wind turbine is operational, it creates turbulence in the wake of its rotor. This turbulence causes a decrease in the wind velocity downstream, reducing the amount of kinetic energy available for capture by subsequent turbines. Consequently, the overall efficiency of a wind farm decreases as more turbines are added.
Understanding the Betz limit is crucial in wind turbine design and optimization, as it sets the upper boundary for the amount of energy that can be harnessed from the wind. Designers and engineers strive to maximize the energy capture from wind turbines while respecting the limits imposed by Betz's law.

Etymology of BETZ
The word Betz is a German surname, often derived from the given name Berthold or Bertrand. The etymology of the given name Berthold originates from the Old High German elements beraht, meaning bright or famous, and waltan, meaning to rule.
