Antifouling and drag reduction of ships are two critical issues in the shipping industry, which significantly affect the efficiency, safety, reliability of ships. Drag reduction by the bionic jet surface is an effective approach for reducing the energy consumption of ships. However, complicated by the impact of marine biofouling, it is invalid to consider the isolated effect of drag reduction of jet surface. Inspired by jet function of shark gills, which have the synergistic effect of antifouling and drag reduction, bionic jet structure model similar to the jet characteristic of shark gills was established. The antifouling function of bionic jet is analyzed, and the ability of drag reduction is also studied with the methods of theoretical analysis and numerical simulation. The jet diameter and velocity of bionic jet surface are analyzed, and numerical simulation is used with SST k-ω turbulent model. The results reveal coupling of appropriate jet diameter and jet velocity was feasible to realize the synergistic effect of drag reduction and antifouling of bionic jet surface.
