Investing churning loss of dip-lubricated gears
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.
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?http://www.cfd-online.com/Forums/mai...s/confused.gif
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,
