利用CFD仿真软件Fluent软件包,对NACA0006翼型的空气动力特性进行了数值模拟分析,采用Spalart-Allmaras模型建立二维湍流模型,利用Gambit生成结构化网格同时加大翼面附近的网格密度。通过研究空气绕流的流动情况,得到在不同工况下翼型周围的压力分布图及速度矢量图。同时,为研究与激波相关的流动现象,采用在计算过程中设置监测点监测求解的收敛性,并采用多种后处理工具验证激波性质的正确性。结果证明,在空气动力学领域中,Fluent是一种行之有效的研究方法。
The aerodynamic characteristics of the NACA0006 airfoil are numerically simulated using the Fluent software package CFD. A Spalart-Allmaras model is used to establish a two-dimensional turbulence model. Gambit is used to generate structured meshes and to increase the mesh density near the airfoils . By studying the flow around the air flow, the pressure distribution and the velocity vector around the airfoil under different conditions are obtained. At the same time, in order to study the shock phenomena related to the shock, the convergence of the monitoring points set in the calculation process is adopted, and the correctness of the shock properties is verified by a variety of post-processing tools. The results show that, in the field of aerodynamics, Fluent is an effective research method.
