“…Recent reviews of the experimental results related to the laminar to turbulent transition are from Morini [1,21] and Hetsroni et al [22]. These studies indicate that the transition from the laminar to the turbulent flow in micro-scale passages could take place at critical Reynolds numbers ranging from 70 [23] up to 10,000 for liquid flows [24].…”

The results of numerical and experimental works dealing with the behavior of gas flow through microchannels are by no means univocal, sometimes agreeing with the classical correlations and other times contradicting them. It is now agreed upon that the effects due to both rarefaction and compressibility must be accounted for. In addition, the experimental works have demonstrated that sometimes compressibility and rarefaction effects can be coupled in microchannels: because these two actions contrast each other, the scatter of the friction factor data for gaseous flows is remarkably large. This paper is aimed

“…The limitation of applying the usual fluid dynamics on a micro liquid-flow has not been known because of effects of a Van der Waals force, an electrostatic force and a steric force (1) . Change in wall shear stresses due to a relation between wall roughness and fluid even in a laminar flow was reported by Mala and Li (2) and Hetsroni et al (3) . This suggests that material of a wall can affect wall shear stress in a micro-tube.…”

Effects of the relative size of a particle to the diameter of a micro-tube on velocity profiles obtained by the micro-PIV measurement of the flow through the micro-tube were investigated to achieve the accuracy of measurements of the flow in a proboscis of a mosquito. The velocity profiles obtained for different diameter-ratios of a fluorescent particle and fused silica micro-tube were compared with the exact solution of the velocity profile of flow through a circular pipe at a low Reynolds number. A suitable diameter-ratio was found to be less than 0.04. The velocity profile of flow through the proboscis of a mosquito measured by using the suitable micro-PIV method satisfying the above condition was found to be different from the exact solution of the circular-pipe flow near the center of the proboscis. The velocity profile in the proboscis was similar to that of a rectangular cross section which was verified by a SEM observation.
