摘　　要：选取双圆弧型风帆,以一艘巴拿马型的散货船作为目标船舶,确定风帆的主尺度。通过CFD仿真优化该帆的气动特性,选取优化后的模型进行风洞试验,对目标船舶加装优化后的双帆,根据CFD仿真结果,讨论来流方向和双帆帆距两个因素对双帆干扰的影响,总结出双帆之间的干扰特性,丰富了风帆助航领域的理论,具有一定的实用意义。The double arc-shaped sail is selected and a Panamax bulk carriers is chosen as the target ship. Then the principle dimensions of the sail are got. The aerodynamic characteristics of the sail are optimized by CFD simulation,and the optimized model is selected for wind tunnel testing. Then the two optimized sails are installed on the target ship. Based on the simulation model built on the CFD,the interferences of flow direction and distance to double sails are studied, interference characteristics are summarized.
