Default magnus effect
Posts: n/a
Hi all,

I'm a newer in Fluent program. I'm going to simulate a flow across a very long rotating cylinder (Magnus effect). I like to siumulate it as a 2D flow so, I would like to know can I use a rotating frame in 2D simulation? or it's more easier to use the other method. Could anybody give some sugestion please?

Thank you in advance?

I am not a Fluent user, but I read this as a fairly general question. There is no need to use a rotating reference frame in your case, in fact, it will only complicate things. If you know how to set up a computation with a stationary (non-rotating) cylinder, then the rotating cylinder should be easy to do. You only need to assign the correct boundary conditions, i.e. the velocities of the wall grid points, on the cylinder surface. Everything else is the same as in the stationary case, and the grid is also stationary.
