摘　　要：采用商业CFD计算软件FLUENT,粘性数值模拟绕一种复杂船型———带球鼻般艏和双艉的丰满船型的流动,通过流线显示辅助改进了船体外形,改善了船体的阻力性能.研究了船型改进前后艉部隧道中纵剖线所处平面的流线分布和船舶总的粘性阻力系数,结果表明改进后的船舶的摩擦阻力系数与ITTC阻力系数公式的计算结果自洽,验证了数值计算方法的正确性和有效性.The viscous flow around a full form ship with bulbbows and twinstern was numerically simulated by commercial software-FLUENT and the local streamlines and total viscous resistance coefficients both the primary ship and the modified ship was investigated. The streamline indicates that the shape of hull gets secondary reformation and the resistance performance of hull is improved. The results showed that the frictional resistance coefficients of the modified ship are in consistant with the ITTC formula results, indicating the verification of numerical calculation method used in this paper.
