Learn CFD from scratch by modeling, meshing, simulating, and validating Savonius wind turbines using ANSYS Fluent with r
What you'll learn
- Understand the basics of wind energy and the working principle of Savonius vertical-axis wind turbines
- Create accurate 2D geometry and apply high-quality meshing techniques in ANSYS, including quad elements, inflation layers, and wake region refinement
- Set up transient simulations for rotating machinery using the sliding mesh approach in ANSYS Fluent
- Capture aerodynamic behavior and performance of Savonius turbines under low-speed wind conditions
- Validate CFD results using real experimental data from Blackwell et al. (1977), ensuring credible simulation outcomes
Requirements
- A basic understanding of fluid mechanics and CFD concepts is recommended. Prior exposure to ANSYS Workbench tools like DesignModeler, Meshing, and Fluent will be helpful but is not mandatory — step-by-step guidance is provided.
Description
This course provides a complete, hands-on guide to performing2D CFD analysis and validationof aSavonius vertical-axis wind turbine (VAWT)usingANSYS DesignModeler,ANSYS Meshing, andANSYS Fluent.
We start with a brief introduction torenewable energy, the role ofwind power, and a comparison betweenhorizontalandvertical-axis wind turbines. You’ll then explore the working principles and applications of theSavonius turbine, which is especially effective inlow wind speed regions.
The course then takes you through a fullCFD workflow, from creating geometry to generating a high-quality mesh, setting up and solving the simulation, and validating your results usingreal experimental data.
You’ll use:
Unstructured quad meshingwithinflation layersfor boundary layer resolution
Body of Influence (BoI)for capturing thewake regionaccurately
Sliding mesh methodinANSYS Fluentfor simulating the rotor’s motion in a transient flow field
Finally, your simulation results will bevalidated against wind tunnel datafrom the classic study:
Blackwell et al., “Wind Tunnel Performance Data for Two and Three-Bucket Savonius Rotors”, SAND76-0131, 1977 — Test Run 21, Configuration No. 9 (Pages 25 & 46)
This ensures that your CFD model is not just theoretical butmatches real-world performance— a critical step in engineering design, research, and reporting.
