摘要

Microscale heat transfer has attracted researchers in the last decade, particularly due to developments and current needs in the small-scale electronics, aerospace, and bioengineering industries. Although some of the fundamental differences between micro and macro heat transfer phenomenon have been identified, there still is a need for further experimental, analytical and numerical studies to clarify the points that are not yet understood, such as the effect of axial conduction, friction factors, compressibility effects, critical Reynolds number, and accommodation coefficients less then unity. The current computational methods for analyses in transition flow and free-molecular flow regimes are ineffective and inefficient. Analyses in these two flow regime are still premature and require more extensive study.
