【摘要】 利用FLUENT求解二维任意剖面在深水中垂向强迫振荡问题。将矩型剖面的垂向非定常水动力计算结果与实验值两者进行比较,结果吻合。在此基础上计算加装组合附体的船型剖面的辐射力,验证了组合附体减纵向运动(文中为“垂荡”)的效果,对深化组合附体优化设计具有重要的参考价值。更多还原

【Abstract】 The author solved the forced-heave of any two dimensional section in the deep water by FLUENT,based on VOF and dynamesh technique.The work of computing unsteady hydrodynamics forces of rectangle section with heaving was done,and the results were tallied with test ones.Furthermore the ship sections with built-up appendage and radiated effect of reducing longitudinal motion-heave were calculated.The work was important in the optimization design of the built-up appendage.更多还原
