Application of the Navier-Stokes equation in Tribology applications

AI Thread Summary
The discussion centers on the application of the Navier-Stokes equations in tribology, particularly in understanding lubrication, wear, and friction in bearings. The equations help determine the forces that maintain a lubricant layer between moving surfaces, preventing direct contact. Participants express the complexity of solving the Navier-Stokes equations, which involve key factors like velocity, pressure, and viscosity. The lack of foundational knowledge in the lecture has left students seeking guidance on how to approach their assignment. Understanding these principles is crucial for effectively applying the Navier-Stokes equations in tribological contexts.

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?

Tribology has to do with lubrication, wear, and friction. Bearings are designed with a layer of lubricant between the surfaces so the actual surfaces do not touch when in motion. The forces that keep the bearing surfaces apart are determined by solutions to the Navier Stokes equation. The NS equations involve velocities, pressure, viscosity and are very challenging to solve.
