Abstract

Control of electroosmosis by an external voltage in capillaries of varying geometry was examined and investigated. Controlled geometric factors included inner and outer radii, external electrode coverage area, and the method of voltage application. The behavior of the flow in response to the external voltage from earlier work and this study were compared to existing literature models. A noticeable lack of correlation between the current modeling theories and the published data is noted. In light of these results, suggestions for further areas of investigation of a description of external voltage flow control mechanism are suggested.
