Hello guys, I'm no doing a nonlinear analysis for a wind turbine blade in Abaqus and encounter a convergence problem. My wind turbine model consists of shell and two webs. Slots are made at the back bottom part of the blade skin. Model as the following pictures showed: conventional...

Hello LiftDivergence, Thanks for your reply. After the post I tried something more with Xfoil. It seems that with scaled coordinates Xfoil could also give meaning results if i scale the Renolds number correctly. For instance: NACA0012 normalized Coord NACA0012...

Dear SparWeb, Thx for your reply. After that post I've tested a little bit with Xfoil by using NACA0012. I've tried to load in the original normalized coordinates, the twisted coordinates as well as the upscaled ones and compare their lift and drag coefficients. It seems that from these tests i...

Hello seepratik, I haven't done simulation about helicopter blade before but have some experience in wind turbine blade design. In wind turbine design there exists also pitch along the blade length. The purpose is to get reasonable angle of attack for each section in the span direction. Suppose...

Hello guys, I'm now doing a project in which a FEM and BEM (Blade Element Momentum) coupled simulation is conducted to study the aeroelastic coupling of a large wind turbine blade(NREL 5MW, with hub connection part). I built the model with Python scripting in Abaqus and for the aerodynamic part...
