I hope you are going very well.
Kindely explain me how to estimate the bending moment from your modele by giving references
I’m not sure I really understand your question. What “model” are you referring to?
Thank you very much for your reaction
In other terms, how it is estimated the blades root bending moment from 5 MW model
I still don’t understand what you are asking. The blade root moments will depend on many things (aerodynamics thrust and torque, gravity, shear, skewed flow, aero-elasticity, etc.). A software such as OpenFAST can be used to predict the blade root moments (and the dynamic response of the entire wind turbine) across different conditions of a wind turbine.
Theoretically, how it is calculated dear Jason, in which method or theory is based. Is based on BEM theory?
The theory basis of OpenFAST has been discussed in many other forum topics, with links to the OpenFAST documentation available here: OpenFAST Documentation — OpenFAST v3.2.0 documentation.
The aerodynamics of OpenFAST include BEM (with many advanced corrections), vortex free wake, and CFD (when coupled to SOWFA or ExaWind).
