โœฆ Synopsis

The transient aspects of electroosmotic flow in a slit microchannel are studied. Exact solutions for the electrical potential profile and the transient electroosmotic flow field are obtained by solving the complete Poisson-Boltzmann equation and the Navier-Stokes equation under an analytical approximation for the hyperbolic sine function. The characteristics of the transient electroosmotic flow are discussed under influences of the electric double layer and the geometric size of the microchannel.

This paper reports an experimental study of the detachment of air bubbles adhered to both upper and lower surfaces of a slit microchannel by shearing flow. The liquid used in the experiments was a base engine oil (MCT-30, Imperial Oil). Microchannels were formed between two parallel glass slides (30

## Abstract The electric double layer (EDL) and electroosmotic flows (EOFs) constitute the theoretical foundations of microfluidics. Numerical solution is one of the effective means of analysis in microfluidics. In general, it is difficult to obtain an accurate numerical solution of complex EOFs be
