Diffusion Coefficient: Effective Diffusion Coefficient

WebA lot of work has been done to predict the apparent diffusion coefficient in porous media. Carman (1939) has shown that, in porous rock, fluids must move on the average at about 45° to the direction of flow (Figure 3‑5). Hence, when fluid has traveled a net distance, L, it has traveled an actual average distance of about √2 x L.

WebDiagram of a bioreactor process showing key factors that can influence kLa values. 3. Air flow rate. Higher oxygen availability drives kLa increases. Increasing oxygen supply to a bioreactor drives this availability and can be controlled by modifying concentration (air vs O 2 enrichment) and volumetric flow. Webthe diffusion rate at normal operating temperatures is too slow to have an effect on device performance. However, when large grain boundaries or large numbers of surface defects exist, the diffusion rate can be fast [2]. Au has a high diffusion factor into GaAs, therefore a Pt or Pd layer is employed to act as a barrier to Au diffusion into GaAs.
