Rotor aerodynamic of wind turbine: In transformation of wind energy, which is formed by heating of different points of the atmosphere by the main energy source sun, to electric energy; wind rotor, which is the first ring in transformation chain, can be designed according to Betz or Glaubert–...
The turbine enables the conversion of wind energy into other forms of energy and is comprised of a horizontal rotor rotating on a mast, the rotor being provided with at least one vertical current tapping blade. The current tapping blade (1) is comprised of two surfaces (2, 3). One of ...
A numerical example of the error estimation procedure is given through the problem of predicting the steady-state temperature of a turbine blade [28]. Finally an Advanced ESM was also presented to increase the applicability of the ESM [46,45]. Simultaneously, a Lumped ESM [46,26] was ...
