Microchannels, liquid, friction factor.Abstract
The main factors influencing the resistance to the flow of liquids in microchannels are the friction factor, the surface tension and the Poiseuille number. In this paper, the liquid itself and the surface properties inside the channel are analyzed from two perspectives. The specific influencing factors are first listed and elucidated, and then their effects are compared and corroborated by citing experimental results from other expert teams. The paper concludes with some relationships between the properties of the inner surface and the fluid resistance: the shape of the cross-sectional area of microchannels plays no important role in the fluid resistance, and the fluid is subjected to greater resistance in hydrophilic and rough inner surfaces. This can provide suggestions and guidelines for the design of microchannels.
