Consider an uniform flow of V = 10m/s passing through a Vertical Axis Wind Turbine (VAWT) as sketched above. The VAWT has a diameter of 12cm and 3 equally spaced blades, each one with a chord length of 2cm. For simplification, consider that it spins with a constant angular velocity of 40 RPM*.

You may use the following simplifications:

 Picture of an actual VAWT 

Solve this problem numerically using ANSYS FLUENT. Present the following results: 

• Velocity magnitude contours 

• Pressure contours 

• Velocity profile at the outlet 

• Stream lines  
• Cp 

• Torque 

Describe what happen downstream of the turbine and think on how that would affect an array of VAWT.
