摘　　要：随着计算机技术的迅速发展,数值模拟已成为帆船帆翼空气动力性能研究的重要工具。利用数值模拟,可实现在较短的时间以内完成多种设计方案的模拟计算,得到帆翼升力、阻力系数等空气动力学特性,为帆船比赛过程中运动员调帆提供技术指导。通过讨论5种湍流模型(S-A模型、standard模型、RNG模型、Realizable模型、SST模型)对于帆翼空气动力性能计算结果的影响,根据与试验结果比较分析,确定了帆翼数值模拟采用Realizable模型。研究结果为下一步数值模拟帆船帆翼空气动力性能打下了基础。With the rapid development of the computer,numerical simulation become an important tool of the research on the aerodynamic performance of the sails.By numerical simulation,many design projects can be done in the short time and it can be obtainable of quantities of the relation of the sail shape to the aerodynamic characteristics,for example,the lift and resistance coefficient of the sails.The article studied how the turbulence model affected the precision of the results.Five different turbulence models were used on the sails.Based on the theoretical analysis and the compare with the experimental results,the realizable model was the best in terms of the both accuracy and robustness,and this model was used to predict the aerodynamic performance of the sails.The research would be contributed to the results of the simulation on the force of sails.
