摘要
为研究滑行艇在波浪运动中的水动力性能,基于STAR-CCM+软件平台,使用VOF方法,结合RNG k?ε模型,通过求解Navier-Stokes方程,对水面滑行艇的直航运动进行数值模拟,得出滑行艇阻力随航速的变化情况及其升沉和纵摇随频率和波长变化的一般规律。将软件模拟值与船模试验值进行比较。研究结果表明:在STAR-CCM+平台上模拟水面滑行艇直航运动水动力性能具有可行性和准确性。
In order to research the hydrodynamics of planning crafts’ motion in waves,numerical simulation calculation was carried out under Star-CCM+ soft-ware platform by using VOF method and RNG k-ε model and solving Navier-Stokes equation.Evolution of planning craft’s resistance was obtained as the velocity change and the amplitude of heave and pitch was changed with wavelength and frequency.The calculation results of Star-CCM+ were compared with ship model experimental results.The results show that numerical simulation of planning crafts direct route motion based on Star-CCM+ is feasible and precise.
