Wind Turbine Blade FSI (Part 1)

Created using ANSYS 15.0, also works with version 14.5

...

This tutorial considers the deformation due to aerodynamic loading of a wind turbine blade by performing a steady-state 1-way FSI (Fluid-Structure Interaction) analysis. Part 1 of the tutorial uses ANSYS Fluent to develop the aerodynamics loading on the blade. In part 2, the pressures on the wetted areas of the blade are passed as pressure load loads to ANSYS Mechanical to determine stresses and deformations on the blade. 

...

In this section of the tutorial, the blade geometry is imported, a mesh is created around the blade and the Fluent solver is then used to find the aerodynamics loading on the blade, the fluid streamlines and the fluid flowtorque generated. Here is more information about the set-up. 

Solver: Pressure-based

Viscous model: The turbulent flow model, k-omega SST

Fluid: Air at standard conditions (15 degree celcius). It's Its density is 1.225 kg/m^3 and it's its viscosity is 1.7894e-05 kg/m*s.

...

              Inlet: Velocity of 12 m/s with turbulent viscosity of 5% and turbulent viscosity ratio of 10. 

              Outlet: Gauge pressure Pressure of zero1 atm. 

              Blade: WallOperating conditions: Pressure at 1 atm.

 Finally, periodics are used to allow the visualization of results for three blades. Here is an example of the results that can be obtained at the end of this tutorial.
