Designing an efficient micro pump is one of the most essential problems in developing micro miniature-sized devices into which multiple functions are integrated, so-called Lab-on-a-Chip or Micro Total Analysis Systems (μ-TAS). A peristaltic pump, in which the channel walls periodically fluctuate in the form of a traveling wave, is believed to be a suitable solution due to its high efficiency, simple structure and low fabrication cost. In this paper, two-dimensional numerical simulation is conducted for a flow in a channel with walls of peristaltic motion and the effect of the amplitude and velocity of the peristaltic wall on the pump performance is studied. Furthermore, the unsteady characteristics of the heat transfer coefficient at the heated wall are also examined.
