Ball and socket joint FSI modelling

[MechEng2010]

Hello all,

Just would like to some input from the engineering world on this.

I would like to model the lubrication film between a ball and socket joint using FE/CFD co-simulations. In reality the ball and socket arrangement would be located in a bath of fluid and the fluid would provide lubrication between the ball and cup (socket). Anyone have any thoughts on modelling this or have experience with this? What sort of boundary conditions would be required? As it is unlike an inlet/outlet fluid flow pipe problem.

Thanks

!</code>The boundary conditions that would need to be specified would depend on the type of analysis you want to perform and the physics you are trying to model. If you want to model the fluid flow, then you will need to specify the boundary conditions for the pressure, velocity, temperature, etc. at the inlet/outlet as well as the wall boundaries. Additionally, you may need to specify the friction between the ball and socket joint as well as the surface tension of the fluid. If you are attempting to model the lubrication between the ball and socket, then you will need to specify the lubricant's properties (viscosity, density, etc.), the contact area, and any other relevant parameters. Hope this helps!
