Hello Simscale community!
I ran a Magnus Effect simulation, basically a rotating cylinder in a steady wind. I need a little help understanding the results. I am trying to calibrate the result against simply ideal force for my cylinder rotation and wind speed. For the diameter 0.089m, the wind speed of 25 m/s and the rotation of 3000 rpm (314 rad/s) and length of 0.5m I should get an upward force of about 240N but I get only 24N. Here is my project directory. Run 2 is the latest.
A few questions and thoughts I have are;
- The force plots give N or Nm. How can I tell which it is?
- I think I correctly selected the surface to compute the force on, the cylinder.
- I am not so concerned with edge effects right now and would like suggestions as to how to efficiently make it a simulation if an infinite cylinder to reduce computation.
- I just want to match basic theory before I experiment with details and changes.
Thanks for any advice or help!
