The simulation model of CFD software is established by taking the experienced parameters[3] µc =0.09, 1c =1.44, 2c =1.92, kσ =1.0, εσ =1.3

These results will be used for comparison with CFD calculations of flow around cooling towers in full scale.

The influence of cell shape, relative density and pore gases on the macroscopic honeycomb thermal properties is investigated by means of transient dynamic computational simulations.
The general purpose CFD package ANSYS CFX 11 was used for the time dependent thermal analysis.
According to these simulations the proper mesh size (l ≈ 0.09 mm) and time step (∆t = 0.1 s and ∆t = 0.01 s in case of considering the convection) were set.
For this purpose transient simulations considering heat conduction in the base material and pore gas have been performed.
The influence of the natural convection was analyzed with additional computational simulations.

Code Verification Verifying mesh independence ensures that CFD results reflect the underlying physics rather than artifacts of grid discretization.

The single-phase airflow is calculated using the commercial CFD package ANSYS-CFX 11.0 in the bearing chamber.
It is assumed that air exited the chamber through the scavenge is negligible and that the discharged air through the vent port only influences local air velocities in the vicinity of this vent, and thus these geometry features are omitted in the CFD calculation.
