摘要
针对钻井船月池附加阻力,开展月池形状对钻井船附加阻力性能的影响研究。通过对不同形状月池内非定常流动特性的研究和钻井船附加阻力的对比分析,探讨月池形状对附加阻力的影响。经CFD分析可知,航行中的钻井船月池内的流体阻塞效应及漩涡运动导致附加阻力增加,优化月池形状和结构可有效降低月池内的波高和漩涡强度,改善航行性能。
In view of the additional resistance of moonpool in drilling vessel,the influence of the moonpool shape on the additional resistance of the drilling vessel is studied.Based on the study of unsteady flow characteristics in moonpools in different shapes and the comparative analysis of the additional resistance of drilling vessel,the influence of the moonpool shape on the additional resistance is discussed.The CFD analysis shows that the additional resistance is increased by the fluid blockage effect and vortex motion in the moonpool of the sailing drilling vessel.By optimizing the shape and structure of the moonpool,the wave height and vortex intensity in the moonpool can be reduced effectively and the navigation performance can be improved.
