The gears are rotating in a crankcase with some partially submerged in a lubricating oil pool. The rotation is fast enough causing oil waving and splash around in the case. I would like to start with calculating with the oil pressure and wall shear resistance forces on the gears with the goal to extract the torque values on the gears.

Questions:
1. What is the latest state of art of CFD simulation in this field?
2. If the interactions and the deformations of the gears are to be neglected, how much can I gain if I just use the "immersed solid" such as in CFX with two phase and free surface without having to go through a full FSI?
3. Are there other more specialized commercial CFD code which might be more suitable for this?
4. Any one willing to share similar experience and/or shed some light on this topic?

Thanks in advance,

Roger
