摘　　要：基于RANS方程,采用VOF方法,选用SST湍流模式,对两艘不同排水量Wigley船同向航行时的水压场进行了数值计算,并开展了双船水压场的实验研究,计算结果与实验结果吻合良好。研究表明:双船在浅水中航行时,由于两船及其引起的兴波相互作用,双船水压场负压峰值和负压延时等特征与两船相对位置密切相关,与单船水压场特征有明显区别。Based on the RANS equation, the VOF method and the SST turbulent flow model are used for the numerical calculation of the hydrodynamic pressure field of two different-tonnage Wigley ships moving in the same direction, and an experimental research on the hydrodynamic pressure field is carried out. The calculated results and experimental results are in good agreement. Studies show that the characters such as the peak value and the delay time of the minus pressure of hydrodynamic pressure field are closely related to the relative positions of the two ships, but different from that of a single ship because of the interaction of two ships and the wave caused by them.
