Hi,

I am studying the profile losses of the rotor. I have created 2D stator and rotor and applied mixing plane between them.

I am confused about axis of rotation while giving frame motion to 2D rotor. In real scenario, the blades are moving in z-axis. However, in my case I have only 2 axis. In which axis, should I apply axis of rotation.

Secondly, I am also thinking about that can I give transnational velocity instead of rotational velocity. Since, it is a 2D domain, each rotor blades pass through the stator with some transnational velocity.
