Rotor Inertia and viscous damping
Hello David,
Currently, I am designing my own Horizontal Axis Wind Turbine (HAWT) and have defined its structure. I need information about rotor inertia and viscous damping. Could you please let me know where I can find this information? Thank you.
Hi Takim,
the rotor inertia is a result of the structural properties that you provided in the structural rotor model. In the structural blade file you can also provide a mass proportial (beta) Rayleigh damping coefficient. In the turbine design module you can also see an overview of the lumped structural properties of yur turbine design.
The viscous damping is a result of the aerodynamic properties in your rotor design. To extract viscous damping properties you could setup some dedicated tests and simulate them such as the decay of some blade motion.
BR,
David
