Reverse engineering was utilized to reconstruct models of blades.
Design and analysis methods for wind turbines are presently based on relatively simple models of rotor blade aerodynamics, such as 2-D blade element/momentum theory (BEMT).
This paper presents a unit commitment (UC) model based on fatigue damage modeling of blades and uncertainty estimation of wind power forecasting (WPF).
The nonlinear multidegree-of-freedom (mdof) model of bladed disk system is analyzed in frequency domain by applying a quasi-linearization technique, which transforms the nonlinear differential equations into a set of nonlinear algebraic equations.
Natural frequencies and natural mode shapes for models of turbine blade assemblies with non-continuous shroud rings are calculated numerically and investigated experimentally.
Two closed-form models of flexible blade coating, named "A" and "B", are presented; they derive from a more realistic one which requires numerical solution and which is used here as standard.
Modeling data of blade riblets exist showing the role of drag and vortex structures.
In order to verify the theoretical model, predictions are compared with experimental results which are obtained from tests with small models of curved blades.
Moreover, by establishing the dynamic model of the blade and casing, the dynamic normal rubbing forces are also calculated under the blade-casing rubbing.
A numerical model of the blade was created using ANSYS Workbench 16.2 in order to estimate the typical mode shapes occurring within the blade based on a wind profile and mass approximating the location where these blades are expected to vibrate.
