Abstract
Microfluidic devices have been applied to many kinds of chemical and biochemical applications including mixin, sorting, enrichment, extraction, heating, and cell cultures. Miniaturization and integration of chemical operations have many specific advantages such as increased speed, efficiency, portability, and reduced consumption through the merits of scale, short diffusion distances and high interface surface-to-volume ratios. The interface does play dominant role on the micro-flow. The non-linear effects of the interfaces cause the non-linear fluid flows. In this paper, several non-linear flow characteristics of the micro-flow will be described, based on the author's experiments. The transient flow analysis is also important to understand the non-linear flow field. The trends of the micro- nano- flow field analysis will be discussed. There will be lots of research topics on non-linear micro- nano- flow.
