Splining turbine for periodic boundary condition

rameezib · June 11, 2013, 07:01

Dear friends,
I wanted to know how to spline the turbine for using periodic boundary condition, i have a rotor with 30 blades, so i know the angle will be 12 degrees, but how to get the curves on the surfaces to be splined, if my suction and pressure side curves are different ?

Turbogrid and bladegen where developed to make exactly this sort of thing easy. Are you using them? Or are you doing it in something else?

Bladegen has provision for only 6 types of turbomachine component, mine is an Impulse turbine, so I'm not able to use Bladegen

Try the geometry and meshing forum. Alternately try the forum for whatever solid modelling package you are using.
