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 computer technology, numerical simulation has become an important tool for the research of aerodynamics of sailing sail. Using numerical simulation, a variety of design schemes can be simulated and calculated in a short period of time. Aerodynamic characteristics such as lift force and drag coefficient of sail wing can be obtained, providing technical guidance for sailors to adjust sail during sailing competitions. By discussing the influence of five turbulence models (S-A model, standard model, RNG model, Realizable model and SST model) on aerodynamic performance of sails, the Realizable model of sailing-wing numerical simulation was established based on the comparison with the experimental results. The results lay the foundation for the next step numerical simulation of the aerodynamic performance of sailing sails.
