Abstract
The competitiveness of component parts made of advanced ceramics results almost exclusively
from the properties of the material in use.
A voxel-based approach for modeling of the material removal as well as CFD-simulation of the unique cooling lubricant flow conditions proved their capability as an optimization tool.
First results of the developed simulation tool are depicted in Fig. 3.
Subsequently a number of different simulations have been carried out applying the CFD-software FLUENT of Fluent Inc.
An additional CFD-simulation in its present version provides another opportunity for qualitative analyses of flow conditions in the otherwise inaccessible contact zone.

The model is incorporated into simulations based on an Eulerian approach.
There is a good agreement between the experimental technique and CFD simulation local solid holdup (εs) at the lower Er values in the magnetically stabilized fluidized bed.
Consequently, the simulations underestimate local solid holdup at high Er values.
Consequently, the simulations underestimate local solid holdup at higher Er values.
The k values from CFD computations are probably underestimated.
