Where can I find a reliable source providing stiffness and damping coefficients for fluid-film bearings, especially elliptical and non-short bearings?
You can find answers in some books on Tribology & Lubrication.
There a book of prof. Someya who presented a lot of examples of calculations of different types of bearings. I cannot give the reference now because I am not at the office.
There is a whole load created by Lund years ago, also you can find them in rotordynamics by goodwin. But the best things is solve reynolds' equation yourself using finite difference : see cameron's book, and then use small perturbation theory to get the coefficients. This is very easy to do and will lead to forces, which you can then use non linearly rather than just linear (old hat now). All is pretty easy if you read RAO, Goodwin and Cameron's three books,

Thank you very much, guys. I've already developed a code in finite elements, but I would just like to validate some new results, using a different reference. By the way, Lund is a very good one. I'm also developing a new code using finite difference that really seems to be more straight than FEM.
Do you have more details about the books (Someya, Rao, Goodwin and Cameron)?
Journal Bearing Handbook, edited by Prof. Tsuneo Someya, published in 1989 by Springer-Verlag:
ISBN 3-540-17074-X
Cameron: lubrication theory
goodwin: rotating machine design
rao: rotor dynamics
a quick search on amazon will find them.
If anyone having e-book of all this author then plz send me on [email protected]
