Hello, everyone.
I am honored to participate in the discussions on the forum. Currently, I am researching the blade icing and its adverse effects on floating wind turbines operating in cold regions. After a period of self-study, I have gained a general understanding of the working principle of OpenFast. But due to my limited knowledge, there are still some issues with running OpenFast. These questions do not involve specific techniques, only requesting some inspiration.
As mentioned earlier, I calculated the ice accumulation of airfoils with different blade lengths under various icing conditions, and obtained the icing mass of the airfoil and the new lift and drag coefficients of the airfoil. I was inspired by the relevant discussions on airfoilprep regarding the correction of lift coefficient and other factors. But what I still don’t know is, where should I make corrections to the blade mass to calculate the impact of additional ice mass on the wind turbine structure (blades)? Additionally, what numerical values (such as torque) can I obtain through OpenFast to assist in analyzing significant ice breaking? Perhaps there have been similar discussions on the forum, but unfortunately, I am still a pure novice in the field of structure. Dear experts, please let me know the relevant discussion titles.
In addition, regarding the hydrodynamic part, in my rough opinion, the slight ice buildup on the blades should not be enough to affect the overall movement of the wind turbine, at least relative to wind and waves. Can we directly use the hydrodyn file from the OpenFast case (r-test)?
Please forgive my poor English.
