摘　　要：为了服务于以低碳排放为主要目标的船型研发和设计,基于计算流体力学(CFD)数值方法,对21万吨大型散货船开展快速性分析。船舶快速性分析包含船体阻力、螺旋桨敞水和船桨自航数值模拟,将数值结果与水池试验进行比较,结果表明:数值模拟的阻力预报误差在1%以内,船桨自航推进效率误差在3%以内,散货船的快速性数值预报精度达到工程应用水平。散货船快速性数值模拟方法可为后续散货船及其他主流船型的研发和设计提供有力支撑。In order to serve the research and development(R&D)of merchant ships and the present goal of low carbon emission,a numerical simulation based on computational fluid dynamics(CFD)are executed to study the resistance and speed characteristics of a 210000 DWT bulk carrier.The numerical simulation including hull resistance,propeller open water characteristic,and ship self-propulsion.The results of present simulation are fully compared with the model test.The results show that the errors of the resistance,and propulsion efficiency between numerical simulation and experiments are respectively within 1%,and 3%.The accuracies of resistance and speed prediction satisfy the requirement of engineering application.The present numerical simulation on the bulk carrier is available for the support to R&D on bulk carrier and other main ships in the future.
