THE INFLUENCE OF FLUID-FLOW ON LEVELING PERFORMANCE

The influence of fluid flow on electrode-shape change that results fro m electrodeposition in the presence of a model, levelling agent is sim ulated and discussed. The treatment is more rigorous than past studies in that flow and concentration fields are recalculated as the electro de shape changes. It is shown that uncertainties due to approximate tr eatments of fluid flow may be as significant as existing discrepancies between experiment and theory. A numerical algorithm necessary to min imize errors associated with automatic grid generation is discussed.
