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.

用于减阻的微通道表面结构

摘要

用于流体输送或传热目的的微通道有许多不同的设计。最具挑战性的问题是选择微通道壁的形状和边界结构，使其满足所有要求，并在高流速下达到最佳和高效。各种研究表明，将超疏水表面应用于微通道壁可以显着降低阻力；然而，超疏水边界条件的最佳表面结构的特征仍然未知。为了澄清这个问题，我们回顾了表面结构选项的不同可能的工程解决方案、它们对减少微通道阻力的影响，并在本文中对它们进行了比较。
