Hi!
I am trying to compute the natural frequency of a system and I also need to add the added mass term to my equation. The object I have is a torus and is basically in heaving motion. I found a good paper, which gives a formula for 3d added mass and 2d added mass. I would figure that I have to use the 3d added mass formula, correct? But when and why do you need to use the 2D added mass? Thanks!

Just give it a little time. Your question is very specific and not general knowledge to most of us.

3D Added mass
A reference to the paper would help as well  or at least some clues about what you mean by "heaving motion of a torus".
