Microfluidics has become an emerging science and technology of systems that process or manipulate small
amount of fluids, using channels with dimensions of tens to hundreds of micrometres. Due to the minute length
scale characterising microchannels, the Knudsen number (???? = ??/??, ratio between the gas mean free path and
the length scale) determine the behaviour of fluid flow. Microelectronic devices generate heat as a result of the
electrical activity of the internal circuitry. In order to minimize the damaging effects of this heat, thermal
management systems have been developed to remove the heat. There is a growing interest in micro-channel fluid
mechanics and heat transfer resulting from the rapid growth of novel techniques applied in microelectro
mechanical systems (MEMS).
