Hi Everyone,
I've been reading about hydrodynamic derivatives and its written everywhere that Nr is large and negative while Nv is small and of uncertain sign. What I want to know is, are these values(large and small) with respect to each other? Or are they with respect to (Mr, Mv, Kr, Kv) or (Yv and Yr non-dimensionalized)? If you can help me out with this, I'd be much obliged. Thanks.
