[Purpose] To reduce the power consumption of high-speed planing boats, [Method] a numerical calculation and analysis method based on viscous fluid mechanics is used to simulate the multiphase flow model of volume of fluid(VOF), and the results are compared with the experimental results of the target ship type. On this basis, the influence of changes in ventilation and speed on the frictional resistance and total resistance of planing boats is studied, and the resistance characteristics of gas bearing planing boats are analyzed. [Result] The results show that when the volume Froude number Fr_▽ is the same, with the increase of ventilation volume, the reduction rates of both total resistance and frictional resistance show a significant upward trend; when Fr_▽≤1.3, the drag reduction rate tends to level off and slightly decrease after reaching a certain value; when Fr_▽>1.3, the increase of ventilation volume leads to a significant increase in the drag reduction rate. At the same gas flow rate, as Fr_▽ increases, the drag reduction rate shows a fluctuating state with obvious peaks and valleys. [Conclusion] The research results can provide some references for analyzing the factors affecting the drag reduction effect of gas reservoirs.
