N2 - Based on the flow field mathematical model of superhydrophobic surfaces, the numerical simulation of superhydrophobic surfaces with microcosmic topography in turbulence was carried out. The flow field characteristics of superhydrophobic surfaces were analyzed from the flow field structure, the shear stress distribution, the velocity distribution of gas-liquid interface and the turbulent kinetic energy distribution. The results show that the superhydrophobic surfaces' microcosmic topography has a significant effect on the near-wall flow field, the shear stress of gas-liquid interface is almost zero, the apparent slip flow appears and the turbulent fluctuation is largely suppressed, which is perhaps the inner drag reduction mechanism of superhydrophobic surfaces.
