Description

Master the power of Computational Fluid Dynamics (CFD) and gain hands-on experience in simulating large-scale wind turbines with this in-depth course on the NREL 5 MW Wind Turbine CFD Analysis with Validation. This course is ideal for engineers, researchers, and students eager to specialize in wind energy simulation and aerodynamic performance analysis.

The geometry is provided in SolidWorks format, allowing you to start directly from ANSYS SpaceClaim for geometry cleanup and domain setup. You will learn how to efficiently prepare the model for simulation and create a high-quality mesh using the watertight workflow in Fluent Meshing, ensuring accuracy and smooth convergence.

After meshing, you’ll move into ANSYS Fluent to perform a detailed CFD analysis under realistic operating conditions, including an inlet velocity of 11.4 m/s and a rotational speed of 12.1 RPM. The course emphasizes validation, where your simulation results are compared with reference data, achieving an exceptional 0.3% error margin.

You’ll also explore how to interpret pressure and velocity fields, evaluate torque and power coefficients, and analyze the turbine’s overall aerodynamic efficiency.

By the end of this course, you will have mastered industry-standard CFD techniques for wind turbine modeling, validation, and optimization — equipping you with practical skills to advance in renewable energy engineering, fluid mechanics research, and aerodynamic design innovation.
