    Gravity vector parallel to rotation axis

    Unspecified Unspecified

      Hi,

      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.

       

      Giuseppe
