Im currently working on a modelling a thrust bearing, and have used the example given in the model phyiscs.
My next step is to find the energy generated by the fluid domain before working out heat transferred to the pad.
The energy equation used being used is 0=d/dy(Kdt/dx) -p(du/dx +dv/dy +dw/dz) +mu((du/dy)^2+(dw/dz)^2)
At the moment I have been wanting to using the energy equations as a PDE, but have been having trouble to get this method to work.
Is one of the in-built physics better suited for this application? And if not how am I best inserting this equation into the PDE solver, so that the pressure and velocity gradient form the pad is first integrated through the fluid and then the energy equations is worked out through the fluid?
Thanks allot,
Ben
