CFD of Contra rotating propellers

Have you worked on contra rotating propeller simulation to know what RPM and Power output you get for particular wind speed? If so, let me know, I need to perform simulations at 5 different wind speeds or more. Only respond if you have experience in simulating contra rotating wind turbine. When you respond, provide your approach on how you would solve this. Without sharing your approach, you will not get response. I'll provide the geometry, you just need to perform simulation in your choice of software e.g. Ansys Fluent, Solidworks, StarCCM, OpenFOAM, Comsol Multiphysics or whatever you have. Also submit actual amount you are seeking and not placeholder bid.
