Hello Fellow Foamers,
I am a novice user of OpenFOAM and for my first project I am simulating a VAWT (H-Rotor with 3 blades). I have executed a couple of simulations for a normal H-Rotor with fixed blades. Now for the final stage, I would like vary the blade's pitch angle, which is thought as a method to increase the rotor's performance. The Blades are to be pitched during the revolution when the angle of attack (aoa) exceeds the stall angle which is 10° in my case. I have tried generating multiple AMIs with snappyHexMesh (1 for the Rotor and 3 for the blades) and implemented the multipleSolidBodyMotion. The combination of motionFunctions I have tried are rotatingMotion (Rotor) with tabulated6DoFMotion (blades) and rotatingMotion (Rotor) with oscillatingRotatingMotion (blades). I would appreciate if anyone who has the same/similar experience with such simulations in OpenFOAM to provide their input. Suggesting a different approach or maybe an improvement to the method I have implemented would be of great help. Thank you! |
