Abstract
There are many different designs of microchannels for fluid transport or heat transfer purposes. The most challenging problem is selecting the shape and boundary structure of the microchannel walls so that they meet all the requirements and be most optimal and efficient at high flow rates. Various studies show that applying superhydrophobic surface to the microchannel walls can significantly reduce drag forces; however, the characteristics of the best surface structure for a superhydrophobic boundary condition are still unknown. To clarify this problem, we have reviewed different possible engineering solutions for surface structure options, their effect on reducing microchannel drag, and compared them in the present paper.
期刊介绍：
Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
