Cyclorotor

Hi, I’m working on my bachelor thesis and I’m trying to highlight the flow inside a cyclorotor. It’s a bit difficult to describe the mechanism but internet is full of videos and info that can explain the topic much better than me.

Basically what I’m trying to achive is a rotating mesh (the main rotor) which rotates at a constant rotational speed and which is connected to 4 blades which rotate as well. The motion of the blades is oscillatory, since they do not complete a full rotation around their respictive axes, but they simply oscillate with alternating positive and negative angles with respect to the tangential direction of the main rotor.

Could you please help me? :slight_smile:

Anyway, thanks for reading and have a nice day!

Hello
thanks for reaching out to us here in the forum.

Based on the video you need to set up either an MRF zone for steady-state analysis, or an AMI zone for transient analysis. You can find how to set up these here:

Hi Sebastian, thanks for your support. I’ve just read the article but I still have some doubts on how to define the rotating zone for each blade. The thing is that each blade-rotating-zone should rotate both around it’s axis and also around the main rotor axis (like a planetary). Is it possible do define such setup?
