    I was given an assignment in my Fluid Mechanics Module with the title:
    Application of the Navier-Stokes Equations in Tribology Applications

    Yet the lecture has given no starting point and we haven't yet done anything to do with Navier-Stokes

    Can anyone help me on where to start?

    not to point out the obvious but is it not covered in whatever text you are using? also what year are you in?

    I think it is with reference to calculations on film thickness and Elasto Hydrodynamic (EHD) bearings where predicts no longer use standard fluid theory. I could give you more information based on your end goals/ideas.

    We only have notes and it's not covered. Everyone in the class was given a different assignment. I'm in 2nd year and our lecturer is not very helpful.

    I got some master tribology notes squirreled away somewhere, let me see if I can find them. There is some information on Bernoulli's and where it does not apply.

    I did a project in college on something similiar. We had to to model couette flow through a fluid film bearing / journal bearing. We just applied the Navier-Stokes equation and modelled the flow in Ansys. Any decent fluid mechanics book will cover the derivation for the Navier- Stokes equation. The book by Cengel covers it.

    Check out fundamentals of fluid mechanics by Munson and Young. It explains the derivation of N-S equations quite well and you should be able to adapt it toyour problem. Alternatively just look for books on tribology, as it is a second year assignment its not going to be extremely difficult and hard to find research. Thep point of your assignment I'm sure is to find teh relevant information. College isn't about being spoon fed information, you do occassionaly have to look things up for yourself
