Hi Folks,
I have four circular inlets in a cylindrical geometry that gives out inflow at an angle. I am trying to find if there is a way to speificy radial and tangential componets of the velocity and give it as a boundary conditions. I understand that the normal way of giving is in cartesion approach in (Ux,Uy,Uz) and I am wondering if tehre is a way to give in cylindrical coordinates, viz., (Ur,Ut,Uz) boundary conditions. Thanks, N.A. |

Do either of you know how to convert from Ux,y,z to tangential and axial velocity's? I am working on a cyclone geometry and would like to convert my results.

I would like to also know how to transform Cartesian velocity components of Fluent (i.e. Ux, Uy and Uz) into cylindrical components (i.e. axial, tangential and radial)

That can be achieved by an easy space-dependent matrix multiplication. You have to look it up in your favorite linear algebra book how it is done.
