Created using ANSYS 2020 R1
Learning Goals
In this tutorial, you will learn:
- the basics of developing a CFD solution using ANSYS Fluent
- how to apply boundary conditions and understand the governing equations behind your solution
- how to develop a a 3D mesh, solve for the flow field, and plot results
Problem Specification
Your project report should include the following. For each item below, also include a short discussion i.e. don’t just present a bunch of figures or equations without any discussion.
- Introduction
- Governing equations and boundary conditions
- CFD simulation procedure including
- Flow domain extents i.e. where you placed the outer boundaries
- Mesh:
- Total number of cells (i.e. control volumes)
- Views of the mesh near and away from the blade
- A discussion of mesh quality
- Convergence history of residuals and integral of static pressure
- Results and discussion including the following:
- Pressure distribution on the blade on windward and leeward sides. Discuss whether the trends agree with your expectations.
- Pressure and velocity distributions around the airfoil section at a few locations along the blade. Sketch in the directions of lift and drag. Discuss the trends in the pressure and velocity distribution, relative magnitudes of lift and drag as well as which segments of the blade are contributing most to the power generated.
- Variation of pressure along the stream-wise axis passing through the hub center. Discuss whether this plot agrees with your expectations.
- Torque and power coefficient. Does the latter seem reasonable? Why or why not?
- Verification. Discuss how one could improve the results from the simulation. You do NOT need to implement the verification steps in the interest of time.
- Conclusion which includes a summary of your results
