Blade Element Momentum (BEM) theory based numerical codes are employed, both in the scientific and industrial field, for designing wind turbines and appraising their performance. Using BEM theory, mono-dimensional mathematical codes can be created. They have very short processing times and high...

The concept of windmill brake state model is considered in this paper. Blade Element Momentum (BEM) calculation often calculates the value of thrust coefficient in windmill brake state. Unfortunately, thrust coefficient predicted by momentum theory deviated dramatically from the experimental...

In this work, a micro wind turbine will be designed and built for a series of wind tunnel tests (rotor dynamics and Wind Turbine (WT) start-up velocity). Its design stems from an original numerical code, developed by the authors, based on the Blade Element Momentum (BEM) Theory.

A new design has been proposed for inexpensive wind turbine blades with high power coefficients.
