N2 - Analysis of Superhydrophobic surfaces is a hot topic recently because of its potential use on drag reduction, lower flow noise, self-cleaning. This paper used VOF model and Lighthill's Acoustic Analogy to simulate the sound pressure of channel flow, and found when fluid flowed across channels, the sound pressure caused by superhydrophobic surfaces was much lower than that of plane surfaces. The macroscale structures and the air stored in the cavities could lower the turbulence kinetic energy, and that could be one of the reasons why flow causes lower flow noise across the superhydrophobic channels.
