| 中文摘要 | Electroosmotic flow is the transport method of choice in microfluidic devices over traditional pressure-driven flow. To date however studies on electroosmotic flow have been almost entirely limited to inside microchannels. This work presents the first experimental study of Joule heating effects on electroosmotic fluid entry from the inlet reservoir (i.e. the well that supplies fluids and samples) to the microchannel in a polymer-based microfluidic chip. Electrothermal fluid circulations are observed at the reservoir-microchannel junction which grow in size and strength with the increasing alternating current to direct current voltage ratio. Moreover a 2D depth-averaged numerical model is developed to understand the effects of Joule heating on fluid temperature and flow fields in electrokinetic microfluidic chips. This model overcomes the problems encountered in previous unrealistic 2D and costly 3D models and is able to predict the observed electroosmotic entry flow patterns with a good agreement. |
