Wind Turbine Blade FSI (Part 1)

Created using ANSYS 14.5

Problem Specification

Overview

This tutorial considers the deformations 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 to ANSYS Mechanical which performs the Computational Structural Mechanics (CSM) to determine stresses and deformations on the blade.

This steady-state 1-way FSI (Fluid-Structure Interaction analysis that uses Fluent+Mechanical) example considers the deformation due to aerodynamic loading of a wind turbine blade. The blade is 27m long with a rotational velocity of 2.43 rad/s. The upstream wind speed is 8 m/s. The Computational Fluid Dynamics (CFD) is performed using ANSYS Fluent to develop the aerodynamic loading on the blade (Part 1 of this tutorial). The pressure on the wetted areas of the blades are the passed as a pressure load in ANSYS Mechanical which performs the Computational Structural Mechanics (CSM) to determine stresses and deformations on the blade (Part 2 of this tutorial).
