Numerical analysis of resistance and motion response of high-speed planing craft
In order to investigate the effects of hull sailing state and motion response on the performance,resistance,and wave resistance of a self-designed planing craft during high-speed operation,a three-dimensional modeling of the craft was conducted using Solidworks modeling software.Based on the Reynolds-Averaged Navier-Stokes(RANS)equations and viscous flow theory,the six-degree-of-freedom motion equations were solved using the coupled Computational Fluid Dy-namics(CFD)software FINE/MARINE.The computational analysis revealed that the resistance of the craft increased gradu-ally within the range of 24 kn to 32 kn,and even after shifting the center of gravity 0.2 m aft,the total resistance of the craft remained relatively stable within the same speed range.At speeds exceeding 30 kn,the motion response of heave and pitch tended to be relatively favorable.The most significant motion response of the craft occurred when it was near a wavelength approximately 16 times the length of the craft.This study provides reference for the speed design and navigation safety strategy of the planing craft.
