Simulations geometry

Later calculations showed that the defect binding energies were invariant to the values chosen for the point charges. As those calculated for the fully-ionic system my be directly compared to those obtained using classical simulation, geometry optimizations were carried out using the fully-ionic point-ions. 

The validation of CFD codes using pressure drop is most reliable when actual experimental data are taken in equipment identical to the situation that is being simulated. Existing literature correlations such as the Ergun equation are known to have shortcomings with respect to wall effects, particle shape effects, application to ordered beds and validity at high Re. The applicability of literature correlations to typical CFD simulation geometries needs to be examined critically before fruitful comparisons can be made. 

The surface free energy, y, is just the free energy for the reaction of Equation 8.32 per unit surface area of the slab. If a slab simulation geometry gives two surfaces of area S ...

Figure 2.16 (a) Schematic of the simulation geometry model for a Nafion-coated HOPG surface (i), where the numbers are indicative of the film-solution interface (1), periodic boundaries from which the step array response can be determined (2a, 2b), step-edge plane (3), and basal plane (4a, 4b), respectively, and simulated concentration profiles for a Nafion-Ru(bpy)3 +... 

To assess the radial distribution of particles in the granulator, horizontal slices were cut out of the simulated geometry. This was done at two different heights, as shown in Fig. 7.51. The thickness of each of the slices is 10 mm. The first slice is situated in the lower part of the Wurster tube, just around the tip of the injection nozzle. The second... 

Since all simulated geometries exhibit different types of flow characteristics and since the direction and velocity of the gas flow can differ from pressure node to pressure node, the conditions within the levitator need to be equal to obtain reproducible data. Otherwise, the variety of flow properties inside the acoustic levitator can influence the drying and reaction conditions.
