    Gravity vector parallel to rotation axis

    Unspecified Unspecified


      it's my first post here, and sorry for my bad english.


      I'm a student and I must study a kinetic turbine (like a peace turbine) in flowsimulation.


      The turbine is in a open channel with free surface but this, in my opinion, is not a problem, because I can change the water lavel in front of the turbine iteratively.


      But the problem is that in the " solvingengineeringproblems.pdf " file there is this sentence: " If you consider gravitational effects in your analysis, the rotation axis must be parallel to the gravity vector. "


      My turbine has the rotation axis horizontal in z direction, but the gravity is in -y direction.


      You know why there is this limitation?

      There is a way to simulate this problem?


      Thank to all.
