ABSTRACT
A numerical model has been developed to simulate three-dimensional and transient electroosmotic °ow oc-curring in various microdevices for handling °uid °ow and transport. The model can simulate one °uid °ow, with or without a free surface, and two-°uid °ow, with or without a sharp interface, using a VOF method. The model is validated by comparing numerical predictions against available analytical solution. Capabilities of the model to simulate processes such as sample focusing, mi-cropumping, and micromixing. are demonstrated through examples.
Keywords: Electroosmotic Flow, Micropump, Micromixer, and Sample Injection
